The door is one of the most important elements to understand the city's history, given its place among the city walls built between the 13th and 14th centuries, designed by Arnolfo di Cambio to better protect the city. The new circle of walls was more solid and with new gates, including that of San Niccolò.
When Florence became capital of a newly united Italy (1865 - 1871), Arnolfo di Cambio's walls were destroyed to make room for new residents.
The Tower is open in the summer months and access is allowed only with guided tours.
