The cathedral serves as the administrative center for the Kolpino deanery of the Saint Petersburg Eparchy.
Svyato-Troitskiy Sobor (Holy Trinity Cathedral) in Kolpino is a prominent Russian Orthodox church located on the bank of the Izhora River. The cathedral was originally constructed in the early 20th century to serve the workers of the Izhorsky Plants. Its architecture reflects the Neo-Byzantine style, characterized by a prominent central dome and arched window designs. The current structure replaced an earlier wooden church that burned down in the 19th century. The interior features traditional iconostasis panels and murals depicting Orthodox saints. The cathedral serves as the main religious hub for the Kolpinsky District of Saint Petersburg. It is an active parish church holding daily liturgy and sacramental services. The building underwent significant restoration efforts in the late 20th and early 21st centuries to return it to its original appearance.
