If you have ever visited the rock formations and caves in Cappadochia in Turkey? You will appreciate this wonderfully unique white town. Its streets are steep and formed from the overhanging rocks. Many of the modern houses occupy natural caves, which may have been the refuge of pre-historic people. The two-story houses have natural rock for roofs and one or two walls.
Visit the calle Herreria, the oldest street in town, that leads town to the river. Other interesting sites are the Arab tower and cistern. Just strolling around town is wonderful, as most areas offer beautiful views of the cave-like houses and surrounding area. The people of this village were the friendliest, of all of my visits in Spain. The town is well worth an overnight stay to get the feel of a Spanish village.
