In the central square of Borovsk stands the Church of the Transfiguration of the Lord "on the hill," built in 1804 by Moscow merchant Vasily Stepanovich Prosvirin. This church was one of the most well-equipped in the city. In 1848, a stone almshouse for women of spiritual rank was erected nearby, with 12,000 rubles allocated for its maintenance.

The last rector of the church was priest Andrei Ivanovich Zharov, born in 1873 in the village of Novo-Skakovo, Kaluga district (now Dzerzhinsky district). In 1900, after graduating from the Kaluga Theological Seminary, he was ordained as a priest and appointed to the Tarusa Holy Trinity Women's Monastery. In 1916, he was transferred as rector to the Church of the Transfiguration on the Hill. In 1937, Father Andrei was arrested and sentenced to ten years in a corrective labor camp.

In the 1930s, the church was closed. After the war, it was converted into a mill, which has partially survived to this day. In the late 20th century, the building was used as a warehouse, and then it was under the management of the municipal unitary enterprise "Sosnovy Bor" until it was handed over to the diocese. People currently reside in the almshouse building at 21 Uritsky Street.

In the late 1980s, conservation work was carried out in the church, including roof replacement. Without regular maintenance, the building gradually deteriorated, and windows and doors were broken.

On February 12, 2001, Archbishop Clement appealed to the regional administration requesting the return of the church to the Church. On December 13, 2001, the church was transferred to the diocese for gratuitous use. Its restoration is being handled by the Annunciation Cathedral under the leadership of rector Archpriest Dmitry Orlov.
