Such towers were very popular all over northern Italy during the medieval ages.
They expressed the wealth of families who built it, but very few remained today.
This tower is in the very center of Bergamo upper town, on the main Piazza Vecchia square.
Entry ticket of 7 Euros includes climbing the top with an elevator, as well a small archaeological museum down.
Views from up (there're two platforms) are stunning, with both upper and lower Bergamo, as well half Lombardy on a clear day
