The interior of Vila Vella is a charming space with narrow alleyways with pebble pavement, which at the maximum splendor moment, it integrated around eighty houses, many of which took advantage of the wall of the fortification as their back house wall.
Built at the beginning of the 13th century with battlement walls, it retains almost the entire original perimeter area. The wall lock distributes four towers and three cylindrical towers completed by mattresses. The best-known towers are the tower of Joanàs, which presides over the bay; the tower of Les Hores, located at the entrance of the courtyard, which owes its name to the fact that it was the only place where there was a public clock, and the tower of Es Codolar, also known as the tower of the Tribute, that presides over the beach of Es Codolar. It is worth mentioning the magnificent voussoiring portal that leads to Vila Vella through the courtyard.
Declared National Historic Artistic Monument in 1931, the fortified enclosure of Vila Vella is the emblem of the municipality. It is currently the only example of a fortified medieval town that still exists on the Catalan coast.
Special mention must be made to the old Sant Vicenç’s church, which has a late Gothic style, built in the 15th century on an earlier Romanesque church dating from the 11th and 12th centuries. It is of a single one and, currently, only the apse and the sacristy conserve the cover.
