The two-story red-brick building, hidden behind residential buildings from Olsufyevsky Lane, was built in 1885 according to the design of architect K.M. Bykovsky for a mental health clinic. The building features large windows and an iron porch, while the garden behind it is surrounded by a tall brick wall.

This clinic became the first in the Clinical Town of Devichye Pole, created at the initiative of Skifosovsky for Moscow University. V.A. Morozova, a well-known Moscow philanthropist, purchased the Olsufyevs' estate for its construction. The old wing of the estate, depicted in Polenov's painting "Grandmother's Garden," was demolished, but the park with its linden alley remained for patients' walks.

V.A. Morozova, born Khlyudova, was married to A.A. Morozov, who suffered from a mental disorder in the last year of their marriage. Morozova treated him at home under the supervision of S.S. Korsakov, a professor at Moscow University and a respected psychiatrist. Korsakov advocated for humane treatment of the mentally ill, rejecting straitjackets and isolation rooms. Morozova's clinic was built according to his methods: windows without bars, but with sturdy ship glass, curtains, drapes on doors, paintings on the walls, and soft furniture in the wards.

Korsakov became the first chief physician of the clinic and actively participated in its design. A library of his books was created in the building.

The clinic's neighbors were the Tolstoy family, who bought a house in Khamovniki in 1882. L.N. Tolstoy often walked in the park, conversing with Korsakov, attended performances organized by patients, and participated in hypnotic sessions. A gate was made between the clinic's park and the Tolstoys' garden.

After Korsakov's death in 1900, the clinic was headed by V.P. Serbsky, and from 1918, by P.B. Gannushkin. In 1925, poet S. Yesenin became a patient of the sanatorium located in several wards and wrote a winter cycle of poems there, including the famous "Maple, you have fallen." Artist M. Vrubel was also a patient of the clinic, and his painting adorned the corridor of the building. In the 1930s, the clinic was renamed in Korsakov's honor, and a bust by S.D. Merkuryev was installed at the entrance. Today, the building belongs to the S.S. Korsakov Clinic, housing a hospital, library, and classrooms for first-year medical students. Unfortunately, the ship glass was recently replaced with double-glazed windows.
