Foundation of the Vladychny Monastery
The Vladychny Monastery was founded in 1360 through the efforts of Saint Alexius, Metropolitan of Moscow, under the patronage of Prince Vladimir the Bold. It stands at Serpukhov, near the confluence of the Nara and Oka rivers in what is now Moscow Oblast.
Barlaam is identified in the tradition as the builder and first abbot of this community. According to the liturgical texts commemorating him, he founded a monastery dedicated to the Entry of the Mother of God into the Temple and served as an instructor of monastics. The principal cathedral bearing this dedication was later rebuilt in limestone during the reign of Boris Godunov.
