The Moura Gate Sq stands just southeast of the cathedral. Near here was the original entrance to town. In the middle of the square is a strange-looking, globular 16th-century Renaissance fountain . Among the elegant mansions around the square is Casa Cordovil , built in Manueline-Moorish style, and have a look across the road to the west at the extraordinary knotted Manueline stone doorway of the Igreja do Carmo .
