Preobrazhensky Old Believers Monastery in Moscow, Religious monastery in Preobrazhenskoye District, Moscow, Russia

The Preobrazhensky Old Believers Monastery is a religious complex in the Preobrazhenskoye District of Moscow featuring traditional Russian ecclesiastical architecture with brick walls and decorative towers. The site consists of multiple buildings arranged within an organized grounds layout.

The monastery was established in 1771 and initially served as a quarantine site during a plague outbreak. It subsequently became a major spiritual center for the Old Believers community.

The monastery is divided into separate sections for men and women, with churches functioning as chapels because the Fedoseevtsy community does not follow traditional priesthood. This arrangement reflects how Old Believers maintained their own religious practices over time.

The territory of the revived Pomorian community at the women's courtyard and the Cross Exaltation Church is usually closed to outside visitors, so do not count on entering. The former men's courtyard with the Dormition Church and the gate Church of the Exaltation belongs to the St. Nicholas Edinoverie Monastery. The site lies by the Preobrazhenskoye Cemetery beyond the Kamer-Kollegsky Val, in the Preobrazhenskoye District.

The male section of the monastery later became St. Nicholas Monastery and housed the Khludov collection of around 1,300 ancient icons and Old Believer texts. This important collection was dispersed or lost during the October Revolution.
