Monastic life and foundations
Before his move north, Demetrius founded the cenobitic monastery of Saint Nicholas on the hill of Saints Boris and Gleb, on the shore of Lake Plescheevo near Pereyaslavl-Zalessk, and served as its hegumen. Influenced by his friendship with Saint Sergius of Radonezh, he later left Pereslavl for a more solitary life in the Vologda forests, traveling with his disciple Pachomius.
After an initial settlement was poorly received, he reached a meander (priluka) of the Vologda River, from which the place took its name, and built a wooden church and cells. The Savior cathedral was completed in 1371, founding the Spaso-Prilutsky (Savior-Priluki) Monastery, which is described as the first cenobitic monastery of the Russian North. Many disciples followed him there from his former community.
