Hospital Sant Pau

Dubbed "The Stone Quarry" for its remarkably sculpted stone facade, Hospital Sant Pau used to be called Hospital de La Santa Creu (Hospital of the Holy Cross & Saint Paul). Founded in 1401 the hospital is actually the results of the coming together of six small Medieval hospitals. Re-built in the early 1900's, the Hospital Sant Pau of today was designed by Gaudi and the building's edifice is considered to be the world's largest abstract sculpture and was declared a heritage sight by UNESCO in 1984. The hospital was fully functioning until June 2009 and it is currently undergoing restoration for use as a museum and cultural center. Since December 2009 there are tours of the hospital being given several times a day, all of which are free. This is a beautiful building, definitely worth checking out especially if you're into architecture.
