The Casas Colgadas (Hanging Houses), also known as Casas Voladas, Casas del Rey is a complex of houses located in Cuenca, Spain. Houses of this kind were frequent along the eastern border of the ancient city in the past. They hang on the cliffs over the Huécar River gorge. Today there are only a few of the houses still there. The most well known is a group of three with wooden balconies. The houses date to the 14th century. Through the years they have been refurbished a few times. The most recent took place during the 1920s. They have been used as individual homes. They have also been used as council houses. Now they are the host to a "mesón", a type of restaurant, and the Museo de Arte Abstracto Español (Spanish Abstract Art Museum), in Cuenca.
