Holy Trinity church at former Cherkasskaya Almhouse, Eastern Orthodox church in Begovoy District, Russia.

The Holy Trinity church at the former Cherkasskaya Almhouse is an Orthodox church at 16 Leningradsky Prospekt, buildings 1 and 2, in Moscow's Begovoy District. Princess Nadezhda Cherkasskaya founded it as a house church for the almshouse she established in 1856 on the former country estate of architect Osip Bove. A chapel of St Nicholas, designed by Nikolai Voskresensky, was added and consecrated on 15 October 1888; in 1893 Pyotr Zykov the Younger replaced the wooden porch with a stone entrance porch and bell tower.

In 1856 Princess Nadezhda Cherkasskaya bought the dacha of architect Osip Bove and set up an almshouse for elderly poor women. She had a house church of the Holy Trinity built there; it was consecrated in 1858. A St Nicholas side chapel designed by Nikolai Voskresensky was consecrated on 15 October 1888, and in 1893 Pyotr Zykov the Younger replaced the wooden porch with a stone one and a bell tower. The church was sealed on 18 October 1921; worship resumed in 2003.

The church serves as a focal point for the local Orthodox community and hosts regular religious services today. Visitors can observe traditional Russian Orthodox worship practices and the routines of daily parish life.

The church stands at 16 Leningradsky Prospekt, buildings 1 and 2, in the Begovoy District, its entrance set back from the avenue. It shares the grounds with the former almshouse buildings, so look for the church among the medical and office structures. Services resumed in 2003 and follow the parish's own timetable.

The church was sealed on 18 October 1921 and its domes dismantled; the premises then housed medical institutions, including a children's polyclinic. Wall paintings from the early 20th century and the Cherkassky burials survived. The building was returned to the Russian Orthodox Church in the early 2000s, restoration followed, and services resumed in 2003.
