In a small church in a quiet part of Madrid is a fresco cycle by Goya from the 1790s.
The church is called San Antonio de la Florida, and the fresco cycle illustrates the miracle of Saint Anthony of Padua.
The cupola is filled with this story, colorful, lively, animated, with characters in typical Madrid-style dress interacting around a painted balcony, under a light-filled sky.
It is definitely off the beaten path in Madrid, but well worth the visit. Check to see that it is open before going, and then finish up with a coffee at the Cafe del Oriente.
