Item 1. Report to Shareholders

The Trust's semi-annual report transmitted to shareholders pursuant to
Rule 30e-1 under the Investment Company Act of 1940 is as follows:

       Welcome, Shareholder

       In this report, you'll learn about how your investment in Van Kampen
       Municipal Trust performed during the semi-annual period. The portfolio
       management team will provide an overview of the market conditions and
       discuss some of the factors that affected investment performance during
       the reporting period. In addition, this report includes the trust's
       financial statements and a list of trust investments as of April 30,
       2004.

       Market forecasts provided in this report may not necessarily come to
       pass. There is no assurance that the trust will achieve its investment
       objective. Trusts are subject to market risk, which is the possibility
       that the market values of securities owned by the trust will decline and
       that the value of the trust shares may therefore be less than what you
       paid for them. Accordingly, you can lose money investing in this trust.

       Income may subject certain individuals to the federal Alternative Minimum
       Tax (AMT).

Past performance is no guarantee of future results. Investment return, net asset
value (NAV) and common share market price will fluctuate and trust shares, when
sold, may be worth more or less than their original cost.

As a result of recent market activity, current performance may vary from the
figures shown. For more up-to-date information, please visit vankampen.com or
speak with your financial advisor. NAV per share is determined by dividing the
value of the trust's portfolio securities, cash and other assets, less all
liabilities, by the total number of common shares outstanding. The common share
market price is the price the market is willing to pay for shares of the trust
at a given time. Common share market price is influenced by a range of factors,
including supply and demand and market conditions. Total return assumes an
investment at the beginning of the period, reinvestment of all distributions for
the period in accordance with the trust's dividend reinvestment plan, and sale
of all shares at the end of the period.

The Lehman Brothers Municipal Bond Index is a broad-based statistical composite
of municipal bonds. The index is unmanaged and does not include any sales

Trust Report

FOR THE SIX-MONTH PERIOD ENDED APRIL 30, 2004

Van Kampen Municipal Trust is managed by the adviser's Municipal Fixed Income
team.(1) Current members include Thomas Byron, Vice President; Robert Wimmel,
Vice President; and John Reynoldson, Executive Director.

MARKET CONDITIONS

The state of the U.S. economy remained mixed over the six-month period under
review. On the positive side, economic growth continued to be robust, with Gross
Domestic Product growth topping 4 percent in both the last quarter of 2003 and,
preliminarily, the first quarter of this year. While this strength in output has
historically triggered fears of rising interest rates, yields remained
stubbornly low across the municipal curve. These low yields were partly the
result of the continued low levels of observed inflation in the U.S. economy.
Unfortunately, they also reflected continuing weakness in the job market, which
remained soft throughout the period. The soft job numbers, coupled with
persistently low inflation, led the Federal Open Market Committee (the Fed) to
maintain its accommodative stance throughout the period.

The surprisingly rapid job growth data released in April, coupled with rapidly
rising commodity and high oil prices, led many investors to fear that the Fed
would be forced to raise interest rates earlier than the market initially
expected. As a result, bond yields across all major sectors spiked in April.

Supply of new municipal bonds in calendar 2003 hit record levels as
municipalities moved to take advantage of historically low interest rates. Many
cities and states sought to reduce expenditures by refinancing existing debt and
replacing it with lower-yielding bonds. In other cases, municipalities attempted
to meet current and future funding needs by issuing new debt. This activity
slowed in the first months of 2004.

The low interest rates that prevailed over much of the period also had an impact
on the demand for municipal bonds. Retail and institutional investor activity
slowed as holders of municipal bonds saw little reason to sell bonds purchased
at higher yield levels and reinvest at lower yields. However, the period was
marked by rising activity among non-traditional investors, such as hedge funds
and insurance companies seeking to take advantage of the attractiveness of
municipal bonds relative to some taxable securities. Additionally, investors'
search for yield led to significant outperformance by lower-rated bonds with
greater credit risk. Sectors such as health care, with a preponderance of
lower-rated issues, performed particularly well.

PERFORMANCE ANALYSIS

Closed-end fund returns can be calculated based upon either the market price or
the net asset value (NAV) of its shares. NAV per share is determined by dividing
the value of the trust's portfolio securities, cash and other assets, less all
liabilities, by the total number of common shares outstanding, while market
price reflects the supply and demand for the shares. As a result, the two
returns can differ significantly. On both an NAV basis and a market-price basis,
the trust underperformed its benchmark, the Lehman Brothers Municipal Bond
Index. (See table below.)

The trust uses leverage to enhance its dividend to common shareholders. The
trust borrows money at short-term rates through the issuance of preferred
shares. The proceeds are typically reinvested in longer-term securities, taking
advantage of the difference between short- and longer-term rates. As yields rose
during the period, the prices of bonds declined. The trust's use of leverage
magnified this negative movement, leading to a slightly lower total return at
NAV than that of its benchmark, which is not leveraged.

Our analysis of the macroeconomic environment, coupled with the levels of
interest rates near multi-decade lows, led us to believe that interest rates
were more likely to rise than to fall further. As a result, we kept the trust's
duration (a measure of interest-rate sensitivity) below that of its benchmark in
order to limit the potentially damaging impact of any increase in interest
rates. This approach hampered the trust's returns for much of the period as
interest rates fell; however, it helped buoy returns when interest rates soared
in the final weeks of the period.

The trust's performance was also modestly hampered by its bias, relative to the
benchmark, toward high-quality securities. Municipal bond investors during the
period responded to the improving economy by reducing the yield spreads between
higher and lower-rated bonds (yield spreads reflect the premium demanded by
investors to buy lower-rated bonds). As a result, lower-quality bonds
outperformed. The portfolio had 82.7 percent exposure to bonds rated AA/Aa or
higher at the end of the period.

We adjusted the portfolio's term structure in anticipation of rising interest
rates. Our research showed that the intermediate portion of the curve offered
the most promising total-return potential. As a result, we focused our purchases
on the 13- to 19-year segment of the curve. Many of the securities we identified

had the added appeal of premium coupons and 10-year call dates, which served to
add income to the portfolio while limiting its interest-rate exposure.

The trust's trading activity during the period was well below traditional norms
because we wanted to avoid having to reinvest into securities with low yields.
That said, we were able to make selective relative-value trades among securities
and sectors as they moved into and out of fair value. Some of these acquisitions
were funded by the proceeds of housing bonds that were called away by their
issuers during the period. In other cases we sold bonds that met their
performance objectives and reinvested the cash into securities with more
promising total-return characteristics.

The trust's portfolio remained well diversified during the period, with its
holdings spread across many major municipal bond sectors. We believe this
long-standing strategy helps to minimize the risk of over-concentration in any
single sector, while also giving the portfolio exposure to as many potential
sources of return as possible. The three largest sector exposures at the end of
the period were general purpose, public education and health care.

As mentioned above, the portfolio's below-market duration served it well in the
final weeks of the period, when interest rates rose sharply. While it is
impossible to predict how long this trend in rates will hold, we believe that
the trust is well positioned to weather further increases in rates. We look
forward to becoming more active in seeking attractive structures and
relative-value trading opportunities now that rates have moved into a more
normal range.

(b) 144A securities are those which are exempt from registration under Rule 144A
    of the Securities Act of 1933, as amended. These securities may only be
    resold in transactions exempt from registration which are normally those
    transactions with qualified institutional buyers.

(c) Security converts to a fixed coupon rate at a predetermined date.

(d) Issuer has filed for protection in federal bankruptcy court.

(e) Non-income producing security.

(f) An Inverse Floating Rate security is one where the coupon is inversely
    indexed to a short-term floating interest rate multiplied by a specific
    factor. As the floating rate rises, the coupon is reduced. Conversely, as
    the floating rate declines, the coupon is increased. The price of these
    securities may be more volatile than the price of a comparable fixed rate
    security. These instruments are typically used by the Trust to enhance the
    yield of the portfolio. All of the Trust's portfolio holdings, including
    derivative instruments, are marked to market each day with the change in
    value reflected in the unrealized appreciation/depreciation. Upon
    disposition, a realized gain or loss is recognized accordingly.

   all shares at the closing common share market price at the end of the period
   indicated.

(c)Ratios do not reflect the effect of dividend payments to preferred
   shareholders.

(d)Ratios reflect the effect of dividend payments to preferred shareholders.

   preferred shares) from the Trust's total assets and dividing this by the
   number of preferred shares outstanding.

(f)Amount is less than $0.01 per share.

VAN KAMPEN MUNICIPAL TRUST

NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2004 (UNAUDITED)

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Municipal Trust (the "Trust") is registered as a diversified,
closed-end management investment company under the Investment Company Act of
1940, as amended. The Trust's investment objective is to seek to provide a high
level of current income exempt from federal income tax, consistent with
preservation of capital. The Trust will invest in a portfolio consisting
substantially of municipal obligations rated investment grade at the time of
investment, but may invest up to 20% of its assets in unrated securities which
are believed to be of comparable quality to those rated investment grade. The
Trust commenced investment operations on September 27, 1991. Effective November
30, 2003, the Trust's investment adviser, Van Kampen Investment Advisory Corp.
merged into its affiliate, Van Kampen Asset Management (the "Adviser").

    The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements. The
preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

A. SECURITY VALUATION Municipal bonds are valued by independent pricing services
or dealers using the mean of the bid and asked prices or, in the absence of
market quotations, at fair value based upon yield data relating to municipal
bonds with similar characteristics and general market conditions. Securities
which are not valued by independent pricing services or dealers are valued at
fair value using procedures established in good faith by the Board of Trustees.
Short-term securities with remaining maturities of 60 days or less are valued at
amortized cost, which approximates market value.

B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Trust may purchase and sell securities on a "when-issued" or "delayed delivery"
basis, with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Trust will
segregate assets with the custodian having an aggregate value at least equal to
the amount of the when-issued or delayed delivery purchase commitments until
payment is made. At April 30, 2004, the Trust had $2,772,450 of when-issued and
delayed delivery purchase commitments.

C. INVESTMENT INCOME Interest income is recorded on an accrual basis. Bond
premium is amortized and discount is accreted over the expected life of each
applicable security.

D. FEDERAL INCOME TAXES It is the Trust's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no provision for federal income taxes is required.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of the Trust's Investment Advisory Agreement, the Adviser
provides investment advice and facilities to the Trust for an annual fee payable
monthly of .60% of the average daily net assets of the Trust. In addition, the
Trust pays a monthly administrative fee to Van Kampen Investments Inc. or its
affiliates (collectively "Van Kampen"), the Trust's Administrator, at an annual
rate of .05% of the average daily net assets of the Trust. Effective June 1,
2004, the administrative fee was reduced from .05% to .00%.

    For the six months ended April 30, 2004, the Trust recognized expenses of
approximately $36,700 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom LLP, counsel to the Trust, of which a trustee of the Trust
is an affiliated person.

    Under separate Accounting Services and Legal Services agreements, the
Adviser provides accounting and legal services to the Trust. The Adviser
allocates the cost of such services to each trust. For the six months ended
April 30, 2004, the Trust recognized expenses of approximately $39,500
representing Van Kampen's cost of providing accounting and legal services to the
Trust, which are reported as part of "Other" and "Legal" expenses, respectively,
in the Statement of Operations.

                                                                              29

excluding short-term investments, were $60,116,170 and $61,101,145,
respectively.

4. DERIVATIVE FINANCIAL INSTRUMENTS

A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate
or index.

    In order to seek to manage the interest rate exposure of the Trust's
portfolio in a changing interest rate environment, the Trust may purchase or
sell financial futures contracts or engage in transactions involving interest
rate swaps, caps, floors or collars. The Trust expects to enter into these
transactions primarily as a hedge against anticipated interest rate or
fixed-income market changes, for duration management or for risk management
purposes, but may also enter into these transactions to generate additional
income. All of the Trust's portfolio holdings, including derivative instruments,
are marked to market each day with the change in value reflected in the
unrealized appreciation/depreciation. Upon disposition, a realized gain or loss
is recognized accordingly, except when taking delivery of a security underlying
a futures contract. In this instance, the recognition of gain or loss is
postponed until the disposal of the security underlying the futures contract.
Risks may arise as a result of the potential inability of the counterparties to
meet the terms of their contracts.

    During the period, the Trust invested in futures contracts, a type of
derivative. A futures contract is an agreement involving the delivery of a
particular asset on a specified future date at an agreed upon price. The Trust
generally invests in exchange traded futures contracts on U.S. Treasury Bonds
and Notes and typically closes the contract prior to the delivery date. Futures
contracts are valued at the settlement price established each day on the
exchange on which they are traded.

    Upon entering into futures contracts, the Trust maintains an amount of cash
or liquid securities with a value equal to a percentage of the contract amount
with either a future commission merchant pursuant to rules and regulations
promulgated under the 1940 Act, as amended, or with its custodian in an account
in the broker's name. This amount is known as initial margin. During the period
the futures contract is open, payments are received from or made to the broker
based upon changes in the value of the contract (the variation margin). The risk
of loss associated with a futures contract is in excess of the variation margin
reflected on the Statement of Assets and Liabilities.

5. PREFERRED SHARES

The Trust has outstanding 12,000 Auction Preferred Shares ("APS") in four series
of 3,000 shares each. Dividends are cumulative and the dividend rate is
periodically reset through an auction process. The dividend periods for Series A
and C are generally 7 days. The dividend periods for Series B and D are 28 days.
The average rate in effect on April 30, 2004 was 1.035%. During the six months

Maintenance" expense in the Statement of Operations.

    The APS are redeemable at the option of the Trust in whole or in part at the
liquidation value of $25,000 per share plus accumulated and unpaid dividends.
The Trust is subject to certain asset coverage tests, and the APS are subject to
mandatory redemption if the tests are not met.
