The Casas Colgadas is a complex of houses located in Cuenca, Spain. In the past, houses of this kind were frequent along the eastern border of the ancient city, located near the ravine of the river Huécar. Today, however, there are only a few of them remaining. Of all of these structures, the most well-known is a group of three with wooden balconies. Their origin remains uncertain, though there is proof of their existence in the 15th century.
