The provincial capital Campobasso, founded by the Lombards, is an active city located at over 700 meters above sea level and divided into the city old and in the new city. The first, with the medieval village, is clinging to the slopes of the Montebello hill while the second, with administrative and commercial function, extends into the underlying plain.

The most important cities in the province are Termoli, railway and motorway junction, fishing port, seaside center and seat of a well-known automobile plant and Campomarino. On the thirty kilometers of low coast, limited between the mouth of Trigno and that of the Saccione stream, the promontory that houses the ancient village of Termoli is detached.

The city is undoubtedly the main center, a well-blended set of history, traditions, culture and tourism. The bathing establishments, the reception facilities, the numerous restaurants with specialised cuisine for fish, the marina from which daily, in the summer, hydrofoils and motor ships leave for the Termites Islands are the main characteristics of the town.

Campomarino, on the other hand, with the medieval and modern center overlooking the wide coast, about five kilometers from the coast, encloses the testimonies of the past in the Church of S. Maria a Mare and in the ancient village that develops around it. The very modern city spans the wide coastline, offering adequate receptivity and well-equipped seaside resorts.
