Monasterio de las Descalzas Reales in Madrid

You're standing at the Monasterio de las Descalzas Reales, right in the old heart of Madrid. The name means something like the Monastery of the Royal Barefoot Nuns. They didn't wear shoes, just sandals. Take a look at the plain façade. It was designed in 1559 by Juan Bautista de Toledo. From out here, nothing gives away the riches hidden behind these walls.
