Located in one of the busiest areas of Madrid, this convent founded by the daughter of Charles V for the ladies of the aristocracy is now home to a remarkable museum of religious art. Seen from the entrance, the main staircase takes on a magnificent appearance. On display in the former dormitory are ten extraordinary 17C tapestries based on cartoons by Rubens. The collection also includes numerous canvases by Zurbarán, Bruegel the Elder etc, as well as some remarkable reliquaries and caskets.
