Holy Trinity Church, Orthodox church in Staraya Russa, Russia.

The Holy Trinity Church is a place of worship in Staraya Russa distinguished by white walls and multiple domes that reflect traditional Russian Orthodox architectural design. Located on Timur Frunze Street, the building stands out in the cityscape through its vertical forms and religious iconography.

A wooden Trinity church on this site burned in 1607. The stone church was built in 1680 at the expense of the merchant Yakov Tverev, using an unfinished building from the late 1660s, and was consecrated on 13 December 1684 by Metropolitan Kornily of Novgorod. After a fire in 1759 and storm damage in 1836, it was rebuilt in 1854–1860 under the architect Konstantin Thon.

The church's name comes from its dedication to the Holy Trinity. A side chapel was added in the 18th century for John Chrysostom, replacing a burnt church. A parish school once taught literacy, arithmetic, church singing and catechism; after the revolution it became a four-year primary school. Services are held daily.

The church can be reached via Timur Frunze Street, with the main entrance on that side of the building. Visitors should note that it functions as an active religious site with regular worship services, so respect for ongoing ceremonies is important.

The building receives protection as a federal cultural heritage site, meaning it falls under state supervision for restoration and preservation. This recognition honors its importance as a historical record of Russian religious and architectural tradition.
