The Savior-Andronikov Monastery
The monastery Andronikos led was founded under Metropolitan Alexis on the bank of the Yauza River in Moscow, dedicated to the Savior and honoring the Icon of the Savior Not Made by Hands. Though dedicated to Christ, the house also came to bear its first abbot's name, becoming known as the Spaso-Andronikov (Savior-Andronikov) Monastery.
Under Andronikos the community became known for its strict observance, and Saint Sergius is recorded as visiting to encourage his disciple's work. The monastery grew into a major center of manuscript production in Muscovy and guarded the eastern approaches to the city. Its surviving Saviour Cathedral, built in the early fifteenth century, is among the oldest preserved buildings in Moscow outside the Kremlin.
