          This Amendment No. 11 amends and supplements the Schedule 13D filed on
May 24, 1996, and amended on July 3, 1996, by Kimco Realty Corporation, a
Maryland corporation ("Kimco"), and Milton Cooper and further amended on May 15,
1997, June 10, 1997, April 30, 1998, September 20, 1999, August 10, 2000, August
23, 2000, August 9, 2001, January 31, 2003 and August 3, 2004 by Kimco, Milton
Cooper and Kimco Realty Services, Inc., a Delaware corporation ("Services") (as
amended, the "Schedule 13D"), relating to the common shares of beneficial
interest, par value $.01 per share (the "Shares"), of Atlantic Realty Trust, a
Maryland corporation (the "Company"). Unless otherwise indicated, all
capitalized terms used herein shall have the meanings given to them in the
Schedule 13D, and unless amended or supplemented hereby, all information
previously filed remains in effect.

ITEM 2.  IDENTITY AND BACKGROUND.

          Information with respect to the executive officers and directors of
Kimco and Services, other than Mr. Cooper, required by Instruction C of Schedule
13D is set forth on Schedule I hereto and incorporated herein by reference.

ITEM 4.  PURPOSE OF THE TRANSACTION

Item 4 is hereby amended to add the following:

          The Company had previously announced that a special committee of the
Board of Trustees (the "Special Committee") was considering acquisition
proposals for all of the Shares or all or substantially all of the Company's
assets. In connection with its evaluation of acquisition proposals, the Special
Committee requested that Kimco and other potential bidders, if interested,
submit proposals to acquire either the Shares or the Hylan Center (as defined in
the Schedule 13D). Kimco has submitted a non-binding indication of its interest
in acquiring the Hylan Center (the "Proposal"). The Proposal is conditioned upon
satisfactory completion of due diligence, negotiation of acceptable
documentation, and any necessary regulatory approvals. The Proposal may be
withdrawn or modified by Kimco at any time for any reason.

          The Company has not accepted the Proposal, and there can be no
assurance as to the Company's view of the Proposal, whether the Proposal will be
accepted, whether any definitive agreement will be entered into if the Proposal
is accepted, nor as to the terms of any such agreement or ensuing transaction.
The Proposal is attached hereto as Exhibit 8 and incorporated by reference 
herein.

          Kimco, Services and Milton Cooper each reserves the right, based on
all relevant factors, and in each case subject to the provisions of the
Standstill Agreement (as defined in the Schedule 13D), to acquire additional
Shares, to dispose of all or a portion of its holdings of Shares, to modify,
amend or rescind the Proposal, to make any alternative proposals with respect to
an acquisition of Shares or assets of the Company, a merger, a reorganization or
any other extra-ordinary transaction involving the Company or its assets, or to
change its intention with respect to any or all of the matters referred to in
this Item 4.





ITEM 6.  CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
TO SECURITIES OF THE ISSUER.

          The response to Item 4 is incorporated herein by reference.
