Castle of San Martino della Vaneza, Medieval castle in Cervarese Santa Croce, Italy

The Castle of San Martino della Vaneza sits along the Bacchiglione River and displays medieval fortification through a central tower and strong walls. The overall layout follows the riverbank and combines military design with its riverside position.

The oldest part, the tower, dates to the 11th century; the castle stood on the border between Padua and Vicenza along the Bacchiglione trade route. It was spared by Ezzelino III da Romano and in 1324 Padua gave it to Nicolò da Carrara for defending the city against Cangrande della Scala. The Carraresi restored the walls and tower battlements. Under Venice it lost military importance but, bought by the Vendramin, became a timber depot for Venetian shipyards, with a floating mill working until the 19th century.

The castle houses a museum dedicated to the Bacchiglione River with archaeological objects spanning several periods. Visitors can see pottery, tools, and other artifacts that illustrate the region's past.

The castle is on the right bank of the Bacchiglione at San Martino di Cervarese Santa Croce, in the province of Padua. The Museo archeologico del fiume Bacchiglione inside is open Wednesday to Sunday, 10:00 to 18:00. Public events such as the Palio dello Sparviero are held here, and private events can be booked.

The fortress was transformed into a river port, showing its economic importance for Venetian trade routes. This shift marks an unexpected change from a defensive structure to a commercial hub.
