The Ostankino Estate Museum is a monument of 18th-century Russian architecture located on the former estate of the Counts Sheremetev, on the grounds of what is now Ostankino Park. The estate complex was formed under Count Nikolai Sheremetev at the turn of the 18th and 19th centuries. The palace-theater built in Ostankino is the only surviving theater building from the late 18th century in Russia, complete with a stage, auditorium, and dressing rooms.

After the Revolution, the count's estate was nationalized and converted into a museum, which by 1938 had been named the Museum of Serf Art. Since 1992, the former Sheremetev estate has been the Ostankino Estate Museum in Moscow.

Restoration work is currently beginning on the central building of the palace-theater, and ACM Group architects were able to inspect the interiors before the work began.
