Colegiata de Nuestra Señora de la Asunción

The Colegiata de Nuestra Señora de la Asunción (Spanish for 'Collegiate Church of Saint Mary of the Assumption') is a Catholic church built in the sixteenth century in the town of Osuna, in Andalusia, Spain. It was founded by Juan Téllez-Girón, 4th Count of Ureña. It was declared Bien de Interés Cultural (Good of Cultural Interest) in 1931.

The interior contains a nave and two aisles, five chapels, and a presbytery. The interior of the church is richly decorated in Renaissance style. It has a Baroque main altar, constructed in the eighteenth century, and the chapels on the sides are all very attractive. In the interior, the huge sacristy is now a museum that exhibits a collection of five paintings by José de Ribera (El Españoleto) and a carving by Juan de Mesa.

On the lower level is the Pantheon of Dukes, which was built in the Plateresque style in 1545 and contains a small chapel with an altarpiece attributed to Roque Balduque, a painting of Hernando de Esturmio, and the tombs of the Dukes of Osuna.
