This kind of snuck up on us. We saw it from atop the city wall and went to check it out. Another great tower to climb. Not as touristy as the towers in Siena and Pisa and a bit more rustic. Incredible view from the top with live trees there for shade. Not a bad climb and the steps are a bit wider than most. Great photo op from the top, which can be a bit crowded. There isn't much space to maneuver around other people up there so be prepared to wait your turn.
