Спасо-Преображенский собор, Orthodox cathedral in Kimry, Russia.

The Transfiguration Cathedral in Kimry is a five-domed, three-altar church built in a transitional style between Russian Revival and Art Nouveau. It consists of a main church, an apse and a refectory, and is crowned by five tented roofs with light drums. The architect Fyodor Rybinsky designed it in 1901 for 1,000 worshippers; besides the main altar of the Transfiguration, it has side chapels of Elijah the Prophet and the Three Hierarchs.

Construction began in 1902 at a site associated with a healing spring that had local religious significance. During the Soviet era the building was repurposed as a cultural center and storage facility before returning to religious use in 1947.

The cathedral serves as the main spiritual center where people gather for worship and religious celebrations. Its five domes and towering silhouette have become defining features of the city's skyline.

The cathedral stands in the centre of Kimry, on the site of a former healing spring, and is reached on foot from the town centre. It is an active parish church of the Tver diocese, so visitors should dress modestly and follow Orthodox custom: men uncover their heads, women may cover theirs with a scarf. Photography inside is best avoided during services.

The building underwent an unusual transformation when repurposed as a craftsmen's hall and grain storage facility during Soviet times, aspects of its past use that remain little known among visitors. This dual function reveals how the structure adapted to changing demands over different periods.
