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 with three interior naves and wooden coffered ceilings. A polygonal apse and stonework taken from an earlier fortress tower on the same site are two of its most visible structural features.
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, giving the building the form it still has today.
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. Visitors who look closely at the entrance can read in these stone figures the authority that local noble families once claimed over the town.
The church continues to serve as the town's main parish and welcomes visitors outside of service times. Plan your visit around regular worship hours, and keep in mind that some areas may be temporarily closed during ceremonies.
The bell tower was designed by Alonso de Vandelvira and has an elliptical shape, which was highly unusual for the period. This sets it apart from the round or square towers that appear far more often in the region.
