Pisa's medieval walls form an impressive 3 km circuit of fortifications amongst Italy and Europe's oldest and best-preserved. Built from 1154 onwards, they stand 11 metres high and feature a walkable rampart path offering panoramic views across the city and towards the Piazza dei Miracoli. You can visit and stroll along the top of these remarkably intact defensive structures, experiencing both the engineering and the vistas that defined medieval Pisa.
