Located in the town of Villanueva de la Reina, with its back to the Guadalquivir river, the Church of La Natividad is a simple building dating back to the beginning of the 17th century, but which houses a number of hidden secrets and small monumental jewels.
The interior consists of two different areas. The first and oldest is at the foot of the church and hides an old Gothic-Mudejar temple with some elements from Al-Andalus including a well and some underground passages. These features appear to have been part of a tower to control river crossings and the old 'Roman Road', and whose main function was as an escape route in case of siege.
The most modern part is structured around floor plan covered by three barrel vaults with lunettes. In the north nave stands the Chapel of El Sagrario, a fine example of Andalusian Rococo from the first half of the 18th century. The main feature of the exterior is the south façade, opposite the Town Hall and a square Opus Isodomum tower.
