The Current Excavations
Following much investigation of the town's sacred and public areas, the current excavations bring into focus the baths complex and propose the beginning of a new relationship with the Soprintendenza per i beni archeologici della Toscana, grounded in both excavation and preservation initiatives.
A Rich History
A Beautiful Setting
Cosa overlooks the modern coastal town of Ansedonia, in the province of Grosseto. It occupies a promontory that enjoys stunning vistas over the Argentario Natural Park and the ancient harbor of Porto Ercole.
