Orbetello
Orbetello The Essential
Built on the central causeway of the lagoon, Orbetello is situated at the end of the main access road to the limestone promontory of Monte Argentario. The fortifications are a reminder of the influence of the Sienese and, later, the Spanish, who made the small town the capital of a ""Presidio"" state of five strongholds. The town's cathedral was built in 1376 on the site of a former Etruscan-Roman temple.
