Historically, some of the first chemistry offices were located in the main building of Saint Petersburg State University called Twelve Collegia. The remainder of these is the Mendeleev museum located on the first floor of the central part of this enormous building. In the 20th century, the Department of Chemistry was headquartered at 41/43 Sredniy prospekt on Vasilievsky Island, about one mile west of Twelve Collegia. In the 1980s, most of the laboratories were relocated to a more spacious building in the newly constructed campus in the suburb of Peterhof.
