São Francisco Square (Praça São Francisco) is an open space surrounded by colonial-period buildings such as the São Francisco Church and convent, the Church and Santa Casa da Misericórdia, the Provincial Palace and other buildings from later periods. The complex is a well-preserved example of typical Franciscan architecture of north-eastern Brazil. On August 1, 2010 the site, which covers 3 hectares (7.4 acres), was selected as a World Heritage Site by UNESCO.
