A light yellow two-story mansion with white pilasters and an expressive portal. Above the entrance door is a window adorned with a column featuring a twisted pattern. The main house of the Golitsyn estate is set back slightly from the alley, surrounded by two wings that face the street. The semi-basement conceals a unique gallery on wide brick arches, and the interiors of the house have preserved tiled stoves and an iron staircase. Research has revealed ancient forms on the facades. It was previously believed that the 17th-century chambers were only preserved on the first floor, but in 2008, restorers discovered that the second and even third floors were also built in the 17th century. This unique ensemble is considered one of the oldest residential buildings. The earliest part dates back to pre-Petrine architecture, created at a time when Russia had not yet looked to the West and was developing its own traditions. There are no more than a hundred such chambers left in Moscow, and half of them are already in ruins. On a spring evening, the Golitsyn estate on Krivokolenny is illuminated. Trees grow in front of the house, all in young greenery. It is quiet. It seems that if one knocks on the front door, the staircase will creak, and an elderly gentleman with a kerosene lamp will open the door. This house has lived a vast life, intersecting different eras. In the early 18th century, the estate belonged to Reingold-Gustav Levol, who became the chief court marshal of Catherine I and played a significant role in the ascension of Anna Ioannovna to the throne. In the 1730s-1740s, the owner was Prince I.A. Urusov, then the 'silk manufacturer' Semyon Myl'nikov, and in the late 1740s, collegiate advisor M.S. Chebyshev, later his daughter E.M. Chebysheva, who married Prince Peter Fyodorovich Golitsyn. The agronomist A.T. Bolotov described him as 'an intelligent, curious man with a large natural cabinet.' In 1822 and 1824, the house was rented for the pension of Ivan Gorn, and in 1827 and 1828, the right wing was rented by Countess E.P. Rostopchina, the mother of the writer Countess de Segur. In 1835, the property belonged to the wife of doctor I.V. Karas, Maria Filippovna, born d'Orrer, daughter of an immigrant and granddaughter of ambassador Charles X in the Vatican. From the second half of the 19th century, rooms were rented here for various institutions: furnished rooms, a music school, a hospital. In 1909, a redesign was carried out to accommodate a printing house and a binding workshop. This printing house employed the poet S.A. Yesenin as a typesetter from the autumn of 1914. The estate is now in an emergency state. The supporting beams under the roof are rotting, there is almost no plaster left on the building, and bricked-up windows are showing through. In the basements, which occupy the area not only under the house but also under the entire inner courtyard, wrought iron grilles have been preserved. The nails and wall ties in the house are also wrought. The inhabitants of this house are students, workers, and janitors. Almost no one lives on the second floor. So much remains undisclosed, so many secrets, and this sends a chill down the spine, while the imagination carries one back to the past, to the confusion of names and events. Sounds of music and fragments of voices can be heard. A strip of light slid down the steps, and the elderly gentleman opened the door.
