Cyril of Beloozero

In 1397, he founded the Kirillo-Belozersky Monastery in northern Russia, in present-day Vologda Oblast.

In 1387, the archimandrite of the Simonov Monastery, Feodor, was appointed as a bishop of Rostov, and Cyril became his successor.

Together with St. Therapont, previously the monk of the same monastery, Cyril left for Lake Beloye.

On arrival, following the advice of Sergius of Radonezh, he first dug a cave, and then built a wooden Assumption chapel and a loghouse for other monks.

Cyril, as the first hegumen, arranged purchases of large areas of land by the monastery.
