The Collegiate Church of Santa Maria de la Asuncion is a very large church in the Plateresque style that is located on the highest point of the hill that overlooks the town. The church was built in the 16th century and was founded by the 4th Count of Ureña and is very spacious. It has a beautiful Baroque main altar and the chapels on the sides are all very attractive. One of the altarpieces was carved by Juan de Mesa. The church has a Sacred Art Museum which allows one to see the five paintings of Jose de Ribera (called El Espanolete), many of which he painted while living in Naples. His paintings are La Crucifixion, Las Lagrimas de San Pedro, San Jeronimo y el Angel Trompetero, El Martirio de San Sebastian, and El Martirio de San Bartolome. There is the famous Panteon Ducal on a lower level that contains the tombs of all of the Dukes of Osuna and their families. This is called the Panteon de Andalucia and is probably the most elaborate pantheon in the region.
