The communal apartment where the dissident satirist Mikhail Bulgakov (1891–1940) actually lived is now a tiny museum that memorializes him and his work. Its iconic address, building number 10 on Bolshaya Sadovaya Street, shows up in most of the writer's work, particularly his most famous novel, The Master and Margarita. The museum includes many items related to that book and its apartment, number 50, located in entrance 6. And be sure to check out the wall of the staircase leading up to apartment 50—it's covered with graffiti and quotes from The Master and Margarita. Located in the same building, but at entrance 1, is the Bulgakov House-Theater, a separate museum. This free museum includes a library of Bulgakov's works, manuscripts by the author, and some of his personal things. The museum also houses a theater whose repertoire includes plays by modern Russian playwrights. Don't be afraid of the big black cat that walks around the premises, it's meant to evoke the famed Behemoth of the novel.
