Holy Trinity Church, Orthodox church in Kursk, Russia.

Holy Trinity Church is a two-storey brick Orthodox church at the corner of Pionerov and Gaidar streets in Kursk, built in the traditions of late 17th-century Russian church architecture. It is a single-domed octagon-on-quadrangle structure with modest decoration; the windows of the drum have complex surrounds. The lower church has three altars, the upper church two, reached by wide, steep staircases in the north and south annexes.

The church stands on the site of a Trinity monastery founded by Boris Godunov's charter of 1597 and burned by Lithuanian troops in 1612. The present brick building was raised in 1742, rebuilt by parishioners in 1782, and enlarged with a north chapel in 1829 and a south chapel in 1842. Closed in 1940, it housed a planetarium from 1989 until the floors were returned to the Russian Orthodox Church in 1992 and 1995.

The lower church has three altars: the Holy Trinity, Ambrose of Optina, and Princes Boris and Gleb. On 6 August 2012, Metropolitan German of Kursk and Rylsk consecrated all three and served the Divine Liturgy. An icon-painting school named after Andrei Rublev was founded at the church in the early 1990s.

Visitors should check in advance since the church serves both for private devotion and formal ceremonies. Photography inside during worship should be arranged beforehand to respect religious practices.

The church is single-domed, not five-domed: a brick two-storey building of the "octagon on quadrangle" type, with modest decoration and windows in the drum framed by compound surrounds. From 1989 to 1995 the building housed a planetarium, and the first floor was returned to the Russian Orthodox Church in 1992, the second in 1995.
