"Resolution of the Central Committee of CPSU, №......... Secret.
August 4, 1975 Copy № 2.
July 26, 1975
№ 2004-A
Central Committee of the CPSU
About demolition of the Ipatiev house in the city of Sverdlovsk.
The various propaganda campaigns around the Romanov family periodically instigated
by anti-Soviet circles in the west, and the former house of merchant Ipatiev in Sverdlovsk
is often referred in this context.
The Ipatiev house continues to stand in the center of the city. Educational centre of
the regional management of culture is placed in it. This house does not represent the
architectural and other values, only a small part of citizens and tourists is showing interest
in it. Recently foreign .......... began to visit Sverdlovsk. In the future the circle of foreigners
could expand, and the house of Ipatiev become the object of their serious attention.
In this case it is expedient to entrust the Sverdlovsk Regional Committee of the CPSU to
resolve the issue of the House demolition in order of planned city reconstruction.
Chairman of the KGB
