During our visit to Siena, we had the opportunity to go up into one of Europe's famous towers without waiting in line for an hour to do so. It's the Mangia Tower and it's 88 meters tall and from there you can see the best views of the city. The climb is difficult, but it's worth it.
Construction on the building started in the 13th century, even though it wasn't finished until the 17th. The white marble sculptured entrance is part of the lower part with windows topped with geometric shapes and its completely different from the upper parts that have huge windows with three bays.
