The area between Khamovniki sloboda and the Convent, once a 1.6 kilometer long stretch of green field used for public festivities, is known as Devichye Pole. In 1884–1897, it was developed in a medical campus of Moscow State University. State-funded clinics, built in strict neoclassical manner, were lined on the northern side of Bolshaya Pirogovskaya Street; privately funded clinics, on the southern side, present a diversity of styles from Palladian architecture to Russian Revival fantasies. In 1905–1914, the city and private sponsors added new educational properties, including nation's largest college for women. At the same time, Moskva River bank north from the campus developed into a strip of factories; more factories and workers followed during 1915 evacuation of industry and workers from Riga. To accommodate these residents, in the 1920s the Bolshevik administration built the Rationalist Usachevka housing project and Constructivist Kauchuk Factory Club.
