Holy Trinity Cathedral, Orthodox cathedral in Shchigry, Russia

Holy Trinity Cathedral is a stone Orthodox church in Shchigry, built between 1796 and 1801 to the town plan approved by Catherine II in 1785. It began as a single-dome church with five bells mounted on posts, later rebuilt as a five-domed church with a tall bell tower and five altars; the bell tower was destroyed in World War II bombing.

The cathedral was built in the 19th century as an Orthodox place of worship and served the community for many years. During the Soviet period, it lost its original purpose and was used as a storage facility until it returned to religious function after the Soviet system collapsed.

The cathedral's name comes from its main altar, dedicated to the Life-Giving Trinity; four side altars honoured the Mother of God (the Burning Bush and Tikhvin icons), Saint Mitrofan of Voronezh, Saint Nicholas and Saint Tikhon of Zadonsk. Since the mid-1990s the Holy Trinity Brotherhood has worked here reviving church crafts, making carved church items.

The cathedral stands in the town centre of Shchigry, Kursk Oblast, and holds services as the seat of the Shchigry Eparchy, established on 26 April 2012. The bell tower destroyed in the wartime bombing has not been rebuilt, so the five restored domes are the landmark to look for. Two side chapels, the central and the St Nicholas ones, were in use by 2007.

The cathedral's five bells originally hung not in a bell tower but on pillars, and the present bell tower was destroyed by German bombing in World War II. During the occupation the building held a stable and a bakery. The domes were rebuilt only in 2007.
