This 7th century fortress on the slopes of Mount Aragats is colloquially known as the “Fortress in the Clouds”. Invaded by the Turks and captured by the Mongols, the site was abandoned in 1236 and lay untouched until excavation and reconstruction began in the 20th century. The basalt castle walls, once lavishly filled with silks, brocades, oil lamps and glistening precious metals, draw many visitors today, as does its bath house.
