Fodor's Expert Review Iglesia de San Mateo
Caceres
Free
Construction on this church began in the 14th century, purportedly over the ruins of a mosque, and took nearly 300 years to finish. The interior is austere, with a 16th-century choir and walls lined with the tombs of prominent Cáceres citizens. The church opens at 10 most mornings, but check with the tourist office in case of changes.
