Real Convento de Santa Clara

Still home to a few Franciscan nuns living in near-total isolation, this Mudéjar-style convent dates from 1340, when it was begun as a palace for Alfonso XI. In 1494, the Treaty of Tordesillas was signed here. A 50-minute guided tour (in Spanish) takes in a wonderful Mudéjar patio left over from the palace, and the church with its stunning techumbre (roof). Other highlights include the Mudéjar door, Gothic arches, superb Arabic inscriptions and the Arab baths.
