Historic Port and Fort Michelangelo
60–90 min · Exterior walk free; interior access varies
Walk the harbour created under Emperor Trajan, including Porta Livorno, Vanvitelli's fountain and the monumental fortress begun under Julius II. Interior access varies, but the harbour ensemble is the city's essential local sight.
Easy
Public harbour routes are generally accessible by day; Fort Michelangelo interiors are not a dependable walk-in attraction and require current local confirmation.
