The neoclassical style of the Royal Basilica of St. Francis the Great dates from the late 18th century and has paintings by Zurbarán and Goya. With its round floor plan, it has the largest dome in Spain and the third largest of its kind in the world. It is built on the site of a Franciscan convent, said to have been founded by Francis of Assisi in 1217. Next door is a quiet and romantic little park with great views of Madrid. The church may be closed if weddings or funerals are in process.
