If you are in Maremma and you want to visit an archeological site, enjoying a cultural experience surrounded by nature, we recommend that you visit the ruins of the city of Cosa, which are located in the town of Ansedonia.

The history of this ancient Roman colony dates back to 273 BC, a date to which reference is made to define the birth of this town center, and took its name from a village that rose a little further, Cusia or Cusi. The town of Cosa, 114 meters above the sea level, is now part of the Orbetello municipality.

Visiting this archeological site will be an opportunity for in-depth knowledge of the history of the place and its inhabitants. Archeological investigations began around 1948 and reveal the presence of one of the most advanced Roman colonies from the point of view of the defensive structure. Cosa, in fact, was founded by the Romans after the surrender of the Etruscan cities of Vulsini and Vulci.

The Romans created the defensive city on the hill of today’s Ansedonia town for strategic reasons, due both to the need to control the surrounding areas from possible attacks (even at the hands of the newly capitulated Etruscans) and to the desire to monitor a large part of the Tyrrhenian Sea. As evidence of an optimal defense, today there are parts of the defence walls, once about 1.5km long, and traces of the 18 towers in the area (17 with a square base and 1 with a round base).

There are also the remains of the three access gates to the city (Porta Fiorentina, Porta Romana and Porta Marina), the road network, public buildings and water supply cisterns located under the houses.

Visiting this site, in addition to the historical and cultural importance of the place, will also give you the opportunity to spend time in the nature and authenticity of this side of Tuscany.
