The very interesting ancient marine town within the neighbouring city of Termoli is characterised by the presence of a peak which includes the typical Old Town, separated by the rest of the city by the dividing walls and the Castle.
Among the monuments and places of interest, the Swabian Castle and the Cathedral are definitely noteworthy.
The Swabian Castle is the town's most representative icon. Its very simple architecture, lacking ornaments, and its defence characteristics allow us to believe it was built during the Norman period (eleventh century), entirely out of limestone and brownstones, close to a pre-existing Longobardic tower. It is however termed Swabian after the restructuring and fortification ordered by Frederick II of Swabia in 1240, following the damages caused by an attack by the Venetian fleet.
Remarkably interesting from an architectural standpoint, the Romanic Cathedral contains the remains of the town's patron saints, Bassus and Timothy.
The ancient Roman town of Vasto still shows traces of the Roman urban texture such as the ancient baths dating back to the 2nd and 3rd centuries where precious mosaic floors have been found.
D’Avalos Palace is one of the most noteworthy examples of Renaissance architecture in Abruzzo. Just next to it are the marvellous Neapolitan gardens overlooking the sea; inside the Palace, the Archaeological Museum proudly showcases a rich collection of very valuable finds.
Saint Joseph's Cathedral contains numerous examples of religious art, a heritage of the presence of the Augustinian Fathers. The walls of the aisle-less, single-nave interior, rebuilt in Gothic style between 1890 and the 1920's, are covered with pleasant mural paintings in neo-Medieval style.
The Amblingh Porch offers magnificent views of the sea and, as a backdrop, the Gargano Cape and the Tremiti Islands.
