Founded in 1131, this is Toledo's oldest convent—and it's still in use. About 20 nuns live here, producing their own sweet wine and some of the best marzipan around. Tucked away in the city's historic quarter, the impressive complex includes ruins of a mosque, on which a chapel was built in the Middle Ages. Also here are the preserved ruins of an Islamic house and courtyard, with an ancient well and Arab baths, and a Jewish house from the same period. Free tours, twice daily, include a visit to the kitchen where the Mother Superior usually lets you sample some sweets. Skip the tourist marzipan shops and buy the real stuff here. There's also an adjacent cultural center with rotating history exhibits.
