Chastye
Chastye was recorded in 1646 at the mouth of the Chastaya, as a settlement of palace peasants attached to Osa. Its name referred to the closely spaced islands that once lay in the Kama nearby. Osa itself had developed as a Russian outpost on Bashkir lands at the end of the sixteenth century. Chastye belonged to the rural world around that frontier settlement, where the Chastaya meets the much larger Kama.
