Porto Ercole

Four fortresses watch over Porto Ercole, a harbour on the eastern side of Monte Argentario: the Rocca grew from a tower of 1296, and the Spanish added Forte Filippo, Forte Stella and Forte Santa Caterina when the port joined the State of the Presidi. Caravaggio is said to have died here in 1610, and the walled old town climbs above a harbour now known for sailing.
