Imagine we suddenly found ourselves sailing on the medieval Pisan fleet — about to be captivated by history. On the horizon: the breathtaking view of the Cathedral of Santa Maria Assunta with the Leaning Tower and other ancient buildings. You’ll see the cathedral with the Baptistery and its bell tower. On the north side, there are parts of the ancient walls, the Monumental gate (called Porta del Leone) and the buildings of the Camposanto and the Ospedale of Santo Spirito. On the opposite side you’ll find the Sinopie Museum and the Museo dell’Opera del Duomo. The visit starts from the tower, which is the focus of the tour and continues to the cathedral and other monuments. From the top of the tower, just for a moment, you could get lost in time to venture into the lesser-known meanders of culture. Please consider that our path starts from the tower, which we will visit, up to its top. In this tour, we will not go into detail of the other buildings of the square, but we will give a general description, to frame the construction in the historical vision of the square itself.
