The Convento de Clausura de la Virgen de la Concepción, an enclosed convent built during the 16th century, is a renaissance transition-style building, although large portions of it have been restored. The church has a basilica form, with a single nave and a 20th century altarpiece with an image of the Immaculate Conception. Among the convent’s remarkable elements is its chapter house, which is remarkable for its dimensions and workmanship. It used to be home to a 14th century sculpture of the Virgin Mary known as La Porterita, which can currently be seen on exhibition at the Dioscesan Museum.
Its exterior consists of a masonry and brick façade, and the upper portion contains the cloister latticework. Facing it is a fountain with an image of the Immaculate Conception.
It is also known as Las Terreras Convent because it is located near Las Terreras Lagoon, which was dried up later due to the unhealthy state that it produced. In 2008, due to a lack of activity, the Conceptionists were transferred to Osuna.
