While you wait for your time slot to climb the almost 300 steps to the top of the 55 meter tall bell tower in the Square of Miracles you can stroll the grassy park and visit the many other monuments available.
The Cathedral, though it has a free entrance still requires a ticket to enter. You can use your Leaning Tower of Pisa ticket for entry.
The Baptistery and Camposanto require separate tickets for entry. These two monuments are exceptional to view from the outside but the inside is even more exciting. Experience the amazing acoustics of the Baptistry and the quiet beauty of the monumental cemetery.
The Sinopie Museum is a quiet reprieve from the busy Square of Miracles which highlights original drawings and artwork from Camposanto found after the near destruction during WWII
The Leaning Tower of Pisa, or rather the bell tower of Cathedral, is probably one of the most visited landmarks in Tuscany made from sparkling white marble and stone.
