The most striking element of medieval Cuenca, the casas colgadas jut out precariously over the steep defile of Río Huécar. Dating from the 14th century, the houses, with their layers of wooden balconies, seem to emerge from the rock as if an extension of the cliffs. For the best views of the casas colgadas , cross the Puente de San Pablo footbridge or walk to the mirador at the northernmost tip of the old town.
