Iglesia de Nuestra Señora de la O, Mudéjar church in Sanlúcar de Barrameda, Spain.
Iglesia de Nuestra Señora de la O is a Mudéjar church in Sanlúcar de Barrameda built with three interior naves and wooden coffered ceilings throughout. The building includes a polygonal apse and incorporates stonework from an earlier fortress tower on the site.
Construction began in 1360 when Isabel de la Cerda Pérez de Guzmán commissioned the church on the site of an earlier fortress. The bell tower was added more than 200 years later, bringing the structure to its current form.
The main facade displays heraldic shields of the Pérez de Guzmán and La Cerda families, held up by sandstone lions with their front paws raised. These stone lions at the entrance reflect the authority that these local families held in the town.
The church continues to serve as the town's main parish building and welcomes visitors outside of service times. Plan your visit respectfully around regular worship hours, and note that some areas may be closed during ceremonies.
The bell tower was designed by architect Alonso de Vandelvira and features an unusual elliptical shape rather than the typical round or square forms. This rare architectural choice from that period makes the tower a distinctive landmark in the town.
