Poteshny Palace: Now a Cathedral
Although you can't visit its interior, it's worth taking a look at its exterior.
A small palace in the Kremlin.
This modest three-storey building was built in 1652 for Boyar Miloslavsky. Subsequent to the owner's death, the building's interior was reconstructed to form a theatre for performing Potekhi, which is an old Russian word to refer to comical performances that gave the palace its current name. The building was used as an office for the police under Peter the Great, and it was turned into the home of the Commandant of Moscow during the 19th century. During this period, the building was reconstructed and its front was transferred to the eastern facade. At the end of the 19th century, during restoration work under the supervision of N. Shokhina, attempts were made to restore the original appearance of the building. The Palace now houses the Office of the Kremlin Commandant.
