After about 1km, pass the Caprilli racetrack and continue past the Naval Academy (1877-81) boundary wall on the left. On the right a series of Art Nouveau villas signal the entrance to the town, which is formally marked by passing through Barriera Margherita (1890), the southern gateway to Livorno. Just past the Naval Academy, the paved cycle path to the town centre begins and goes past Piazza San Jacopo in Acquaviva and the church of the same name, which is wonderfully positioned on the seafront. You can make a stop here in the piazza for a snack and to admire the sea view. Visit the church of San Jacopo, the IV century crypt is one of the oldest buildings in the town.
