Although it is not a big city (counts around 50 000 residents), Cuenca is actually the capital of the homonymous province of Spanish autonomous community Castilla-La Mancha. This town is particular because it was built on top of steep rocks at an altitude of 956m, and on top of that (no pun intended) the town was listed as UNESCO World Heritage due to well preserved cultural infrastructure. The main monument in Cuenca is Cathedral of Our Lady of Grace, also known as the first gothic cathedral in Spain. The central square is called Plaza Mayor where you will see baroque Town Hall.The most famous part of Cuenca are the so-called las casas colgadas or the "hanging houses", the example of the traditional Cuenca houses built on the rocks. Today some of them house restaurants and the Museum of Abstract Art.
