 Its name is derived from "pedra tallada", meaning 'carved stone'.Declared a historic-artistic monument, most of the buildings are built from stone carved from the fosse or moat which still encircles parts of this small fortified medieval town.The privately owned Castle of Peratallada is the dominant structure in the center of the town, with a 13th-century Romanesque church dedicated to Sant Esteve (Saint Stephen) outside the town walls.
