Porta XX Settembre is the last door to be opened in the walls. In fact, at the end of the nineteenth century, with the construction of the railway and the station of Montagnana, it was considered essential to open a sufficiently wide passage in the walls. It was the need to have a direct outlet as close as possible to the station that led the administrators of the time to make this decision.
Before the start of the works, the famous architect Camillo Boito was consulted, who proposed to preserve the corresponding tower in any case. It was therefore decided to break through only the wall of two arches, preserving the same and the walkway above. The outcome of the operations led to the cancellation of some architectural details (for example the holes of the vents in the battlements, the holes and the modillions of the tower), but, for the time, it is to be considered the least traumatic solution that could be adopted.
