The old town is surrounded by the "Contramurada", the street which runs around the town and where originally the walls of the olds city stood.It is a maze of narrow streets of Arabic and medieval origins. Within the old quartes of the town we find the most important monuments. The street which runs between the "Plaza del Borne" and the "Plaza de Alfonso III", the old Mahón entrance, is the most pedestrian area of the city. Here we find the arcades, popularly called "Ses Voltes" which start at he Plaza de la Catedral and constitutes the comercial center of the old city.
