Borshchov Manor, Kostroma, Classical manor building on Susaninskaya Square, Kostroma, Russia.

Borshchov Manor is a classical building on Susaninskaya Square featuring white columns and balanced window arrangements across its facade. The structure contains multiple rooms with decorative moldings and ornamental details characteristic of Russian manor architecture from that period.

Lieutenant-General S. S. Borshchov began a stone wing on his estate on Yekaterinoslavskaya Square in 1819; the main classicist mansion followed in 1824 to a design by provincial architect N. I. Metlin. Nicholas I and Tsarevich Alexander II, with tutor Vasily Zhukovsky, stayed here in 1834. Damaged by the 1847 fire, the house was sold unfinished to merchant A. A. Pervushin, who repaired it and ran the Hotel London; the city bought it in 1870 and rebuilt it for the district court.

The building's name comes from Lieutenant General S. S. Borshchov, who began a stone wing here in 1819. After the 1847 fire, merchant A. A. Pervushin opened the luxurious London Hotel in the rebuilt house; in 1870 the city bought it and converted it for the district court, moving the hotel across the street.

The manor stands at the corner of Susaninskaya Square and Shagova Street, address Shagova 1. Its main entrance with the ceremonial vestibule is on Shagova Street, while the eight-column portico faces the square. A four-column portico marks the side facade along Mira Avenue. The building is now occupied by the regional court, so interior visits are not available; the facades can be viewed from the square.

In 1852 the merchant A. A. Pervushin offered the rebuilt house to the city for 25,000 silver rubles as premises for government offices; the deal dragged on until Minister of the Interior S. S. Lanskoy rejected it in 1857, ordering the money to go to building four new prisons in Kostroma Governorate. Pervushin then opened the luxurious hotel "London" in the building.
