The church was constructed between 1534 and 1539 to serve as a collegiate institution.
It contains the 'Pantheon of the Dukes of Osuna,' a subterranean vault that functions as a funerary chapel for the Téllez-Girón lineage.
The sacristy holds five original paintings by José de Ribera, often referred to as 'Lo Spagnoletto'.
The architecture follows the principles of the Italian Renaissance, moving away from the preceding Gothic styles prevalent in the region.
The church was granted the title of 'Collegiate' by a papal bull in 1535, giving it a status superior to a standard parish church.
The 'Patio del Santo Sepulcro' serves as the church's unique Renaissance cloister, featuring intricate column carvings.
The site was once part of a larger planned educational and religious complex that included a now-defunct university.
The Collegiate Church of Our Lady of the Assumption in Osuna is a 16th-century Renaissance monument commissioned by the fourth Count of Ureña, Juan Téllez-Girón. It replaced an earlier parish church and serves as the funerary pantheon for the ducal house of Osuna. The structure features a distinctive plateresque facade and an interior organized around a central courtyard. The sacristy houses a notable collection of religious art, including works by José de Ribera. Beneath the main altar lies the pantheon, which contains the burial vaults of the noble family. The building is constructed of local sandstone, characteristic of the region's architectural heritage. It stands atop a hill overlooking the town and surrounding Sevillian countryside.
