Church of the Transfiguration, Neoclassical cathedral in Torzhok, Russia

The Church of the Transfiguration is a five-domed Orthodox cathedral with Doric porticos, built in the Empire style on the bank of the Tvertsa River in Torzhok. It forms an ensemble with the adjoining Church of the Entry into Jerusalem, a single-domed warm church added in 1841–1842. The two buildings contrast and complement each other.

A wooden church on this site was first mentioned in 1163 and burned in 1238 during Batu Khan's invasion. A stone church built in 1364 with donations from Novgorod and Tver merchants stood until 1815, when the dilapidated building was dismantled. The present cathedral was built between 1815 and 1822; local historians suggest the design may be by Carlo Rossi, though this is not confirmed. Services stopped in 1930 and the bell tower was demolished.

The cathedral combines Russian Orthodox traditions with neoclassical design elements typical of the Russian Empire era. This blend appears in its columned porticos and geometric layout, visible to anyone walking around the exterior.

The cathedral stands on the site of the former kremlin on the bank of the Tvertsa. It is a working church again since 2018, so access may be limited during services. The neighbouring warm Church of the Entry into Jerusalem, built in 1841–1842, stands on the south side.

The cathedral's architect is not documented: local historians suggest the Moscow architect Carlo Rossi, but the project may derive from the Ascension Church at Tsarskoye Selo, built in 1788. Construction was supervised by Ivan Mokshev. The bell tower was demolished after services stopped in 1930.
