                  dated July 29, 1996               

Ladies and Gentlemen:

            We have served as Maryland counsel to Vornado Realty Trust, a

as amended (the "1933 Act").  The Shares are to be issued by the Company
pursuant to the Vornado Realty Trust 1993 Omnibus Share Plan, as amended
(the "Plan").  Capitalized terms used but not defined herein shall have the
meanings given to them in the Registration Statement.

            In connection with our representation of the Company, and as a
basis for the opinion hereinafter set forth, we have examined originals, or

            2.    The Amended and Restated Declaration of Trust of the

            3.    The Bylaws of the Company, certified as of a recent date
by its Secretary;

            4.    Resolutions adopted by the Board of Trustees  relating to
the approval the amendments to the Plan and minutes of the meeting of

approved, certified as of a recent date by the Secretary of the Company;

            5.    Resolutions adopted by the Board of Trustees of the
Company relating to issuance and registration of the Shares, certified as

            6.    A specimen of the certificate representing a share of

            7.    A certificate of the SDAT as to the good standing of the

            8.    A certificate executed by Susan D. Schmider, Secretary of

            9.    A copy of the Plan, certified as of a recent date by the
Secretary of the Company; and

            10.   Such other documents and matters as we have deemed
necessary or appropriate to express the opinion set forth in this letter,
subject to the assumptions, limitations and qualifications stated herein.

            In expressing the opinion set forth below, we have assumed, and
so far as is known to us there are no facts inconsistent with, the
following:

            1.    Each of the parties (other than the Company) executing
any of the Documents has duly and validly executed and  delivered each of
the Documents to which such party is a signatory, and such party's
obligations set forth therein are 


 3

legal, valid and binding and are enforceable in accordance with all stated
terms except as limited (a) by bankruptcy, insolvency, reorganization,
moratorium, fraudulent conveyance or other laws relating to or affecting
the enforcement of creditors' rights or (b) by general equitable
principles.

            2.    Each individual executing any of the Documents on behalf
of a party (other than the Company) is duly authorized to do so.

            3.    Each individual executing any of the Documents, whether
on behalf of such individual or another person, is legally competent to do
so.

            4.    All Documents submitted to us as originals are authentic. 
All Documents submitted to us as certified or photostatic copies conform to
the original documents.  All signatures on all such Documents are genuine. 
All public records reviewed or relied upon by us or on our behalf are true
and complete.  All statements and information contained in the Documents
are true and complete.  There are no oral or written modifications or
amendments to the Documents, by action or conduct of the parties or
otherwise.

            5.    The Shares will not be issued in violation of any
restriction or limitation contained in Section 6.6 of the Declaration of
Trust.
 
            The phrase "known to us" is limited to the actual knowledge,
without independent inquiry, of the lawyers at our firm who have performed
legal services in connection with the issuance of this opinion.

            Based upon the foregoing, and subject to the assumptions,
limitations and qualifications stated herein, it is our opinion that:

            1.    The Company is a real estate investment trust duly 
formed and existing under and by virtue of the laws of the State of
Maryland and is in good standing with the SDAT.

            2.    The Shares have been duly authorized for issuance
pursuant to the plan and, when and if issued and delivered against payment
therefor in the manner described in the Plan, the


 4

Registration Statement and the resolutions of the Board of Trustees of the
Company authorizing their issuance, will be (assuming that any shares of
beneficial interest issued between the date hereof and the date on which
the Shares are actually issued (not including any Shares), when aggregated
with all shares of beneficial interest issued as of the date hereof and the
Shares, will not exceed the total number of shares of beneficial interest
that the Company is authorized to issue) validly issued, fully paid and
nonassessable.

            The foregoing opinion is limited to the substantive laws of the
State of Maryland and we do not express any opinion herein concerning any
other law.  We express no opinion as to compliance with the securities (or
"blue sky") laws or the real estate syndication laws of the State of
Maryland.

            We assume no obligation to supplement this opinion if any
applicable law changes after the date hereof or if we become aware of any
fact that might change the opinion expressed herein after the date hereof.

            This opinion is being furnished to you solely for submission to
the Securities and Exchange Commission as an exhibit to the Registration
Statement and, accordingly, may not be relied upon by, quoted in any manner
to, or delivered to any other person or entity (other than Sullivan &
Cromwell, counsel to the Company) without, in each instance, our prior
written consent.

            We hereby consent to the filing of this opinion as an exhibit
to the Registration Statement and to the use of the name of our firm
therein.  In giving this consent, we do not admit that we are within the
category of persons whose consent is required by Section 7 of the 1933 Act.

                           Very truly yours,
                                 

                           /s/ Ballard Spahr Andrews & Ingersoll
