It’s really a cute architecture, full of history, but they are still working on it, the top floor is not available yet so you can’t really have a panoramic view, to climb the tower, it’s 3 euro per person, which if you hope to see something,I don’t recommend you to get in,there’s nothing to see inside, except nests of doves and some dusts inside , unless you just want to contribute to the maintenance of this cute architecture
