The great fortress, Rocca di Ponte di Torre, was strategically located to guard and defend a fluvial crossing and the road that led from Este to Montagnana.
The historical record of this military building dates from the first half of the 13th century. It was reconstructed and enlarged by Ubertino da Carrara at the same time as the castle of Este. The present building preserves its 14th-century appearance and consists of walls and a 24-metre-high quadrangular tower covered by a pyramidal roof, which was restored in the 1990s.
Following Este’s commitment to Venice, the fortress lost its strategic function and was sold to the Comunità of Este at the end of the 16th century.
