In Moscow, two museums honor the memory of Mikhail Bulgakov and "The Master and Margarita". Both are located in Bulgakov's former apartment building on Bolshaya Sadovaya Street, No. 10. Since the late 1980s and the fall of the Soviet Union, the building has become a gathering spot for Bulgakov fans, as well as Moscow-based Satanist groups. Over the years they have filled the walls with graffiti. The best drawings were usually kept as the walls were repainted, so that several layers of different colored paints could be seen around them. In 2003, all of the numerous paintings, quips, and drawings were completely whitewashed.
