Next to Chiesa di Sant'Agostino, a steep path known as Via della Rocca leads up to what remains of Piatrasanta's ancient fortifications. The crenallated city walls date to the early 1300s and what remains of Palazzo Guinigi was built as a residence for signore of Lucca Paolo Guinigi in 1408. Views of the city and deep blue Mediterranean beyond are predictably worth the short climb.
