Savvaty of Solovki was a 15th-century Russian monk who sought extreme solitude for prayer. After living at the Kirillo-Belozersky Monastery, he traveled to a deserted island in the White Sea in 1429 to find more seclusion. Accompanied by a hermit named German, he established a small cell and a cross on the island. His efforts laid the foundation for the later establishment of the Solovetsky Monastery, which was built by subsequent monks following his death in 1435.
