Colegio Nacional de Monserat by mikegr
Many of the university buildings are open to tourists for guided tours or just to wander around.The Colegio Nacional de Monserat dates from 1687 (although only in its present location from 1782).
Take the time to look inside and you will find a couple of pleasant courtyards, a small museum containing astronomical instruments and beautiful tiled coridors.
Worth a look.
