Saint Sergius Church near Moscow Gate, Byzantine temple near Moscow Gate, Tula, Russia.

Saint Sergius Church is an Orthodox church in the Zarechensky district of Tula, near the former Moscow Gate. It began as part of a charitable complex: two two-storey brick buildings erected in 1892–1893, with a church added later. A bell tower that once stood beside it held a library and a hall for religious readings; it was demolished in the 1930s.

The church was built to honor Saint Sergius of Radonezh, a major religious teacher from the 14th century in Russia. This building connects to the history of Russian monasticism and regional spiritual development.

The church takes its name from Saint Sergius and reflects the spiritual role this place holds for the local community. Visitors can observe the religious services that continue to shape daily life in this neighborhood.

The church is easily reached from the Moscow Gate area and open to both visitors and worshippers. Since it is an active place of worship, visitors should dress respectfully and behave thoughtfully when inside.

The first rector, Archpriest Mikhail Rozhdestvensky, was buried inside the church on its north side on 9 August 1915; he had supervised the charitable complex from its founding in 1891. The bell tower that once held a library and a hall for religious readings was demolished after the church closed in 1930.
