Кирилло-Белозерский монастырь
The Solovetsky Monastery was founded in 1436 by the monk Zosima, however, monks Herman and Savvatiy from the Kirillo-Belozersky Monastery lived on the island from 1429 to 1436, and are considered to be co-founders of the monastery. Zosima later became the first hegumen of the monastery. After Marfa Boretskaya, wife of the posadnik of Novgorod, donated her lands at Kem and Summa to the monastery in 1450, the monastery quickly enlarged its holdings, which was situated strategically on the shores of the White Sea.
