Near Bakhchysarai (west Crimea) is the location of an ancient city called Eski Kermen. It is famous for more than 300 caves, which had been inhabited since the sixth century.
It was a shelter for people in medieval times. Several rock grottos took on the role of temples in which the faithful prayed.
Frescoes depicting Christ and Mary have remained inside the caves.
Over the centuries, the population gradually increased and later there were several hundred people.
The area was inhabited until the arrival of the Mongols in the fourteenth century.
