Las Casas Colgadas, Casas Voladas or Casas del Rey, are a group of civil buildings located in the city of Cuenca.

They are so named because they have a cantilevered part of them, or large balconies, protruding from the high rocky cornice of the Huécar river gorge.

The only three examples of this type of building that still survive are the "Casa de la Sirena" and the two "Casas de los Reyes", built between the 13th and 15th centuries.

These buildings, together with its Gothic cathedral, contributed to the walled city of Cuenca being named a World Heritage Site in 1996.

The graphic history of these buildings begins in 1565, the year in which the Flemish painter Anton van den Wyngaerde includes them, along with the entire San Martín cornice, in his splendid Cuenca from the east.

The oldest photographs of the place, dated to the last third of the 19th century, show us that the complex remained almost intact for several centuries, although, unfortunately, little remains of that architectural and landscape wonder of the old Cuenca.

There is evidence that they were built in the 15th and 16th centuries.

Throughout its history they have undergone various renovations, the most recent being those carried out during the 1920s, when there were still eight, and in 1966 due to the high state of degradation of those that remained standing.
