Visit the 800-year-old cathedral, Colegiata de Santa Juliana, Calle Santo Domingo (tel. 94-281-80-04), which shelters the tomb of the village's patron saint, Juliana, and walk through its ivy-covered cloister. Among the treasures displayed are 1,000-year-old documents and a 17th-century Mexican silver altarpiece. It's open daily 10am to 1:30pm and 4 to 7:30pm. In winter, it closes at 6:30pm and is not open on Monday. The 3€ ($3.90) admission includes the Convent of the Poor Clares.
At the other end of the main street, the 400-year-old Convento de Regina Coelí, also called the Convent of the Poor Clares (Museo Diocesano; tel. 94-281-80-04), houses a rich art collection inspired by a Madrid art professor who encouraged the nuns to collect and restore religious paintings and statues damaged or abandoned during the Spanish Civil War. The collection is constantly expanding. The convent is open Tuesday to Sunday 10am to 1:30pm and 4 to 8pm (closes at 6:30pm in winter).
