One of the most famous monuments of Lucca
This tower is one of the most famous monuments of Lucca, and one of the few medieval towers still standing strong. It was built in 1390 by the Guinigi family (rich bankers from Lucca) as a demonstration of their power and prestige. What stands out about this tower is the oak garden on top of it, which you can visit (by going up 231 steps) and find beautiful views of the city. If I remember correctly, the entry fee is 3.50€.
