Naval history isn't written only on the high seas. A very rich culture exists among the inland waterways. The River Navigation Museum (Museo della Navigazione Fluviale) in the town of Battaglia Terme was specifically created to record the maritime history of the network of canals in the lower Po Valley. It is located in the Ortazzo quarter on a strip of ground at the junction of the Rialto and Vigenzone Canals. The Upper Adriatic interior is a complicated web of rivers and canals, and this amphibious characteristic is clearly illustrated in Battaglia Terme, located on the low plain between the Euganei Hills and the Venetian Lagoon. Important river navigation routes cover the area, along with lesser itineraries connecting houses and small villages, built in the agrarian countryside over the centuries. This is the environment where the Museum was placed, with the purpose of conserving the neglected patrimony of inland nautical tradition and the amphibian knowledge linked to inland navigation, the smaller shipyards, ports, fishing and costal settlements. Riccardo Cappellozza is the projects deus ex machina, a third generation waterman with a passion for traditional river navigation and a collector of construction and piloting artifacts of the past. He had the idea for a permanent museum in the 1970's, but was unable to fulfill his dream until 1999 when the town's renovated ex-slaughterhouse was assigned custodian of local nautical traditions. The ground floor of the museum hosts the river craft, with elements of the vessels showing their construction characteristics and highlighting the different typologies used for cargo and human transport. The second floor is dedicated to methods of propulsion. Before the advent of inboard motors, cargo vessels were propelled by sail, towed by horses, or rowed with long oars by the watermen. The museum exhibits traditional propulsion methods, along with mechanical components like propeller shafts, propellers, gearboxes and navigation lights. Particularly interesting are the shipyard tools from the once numerous river yards where shipwrights, ironsmiths, caulkers, woodworkers and many others were employed. ... follows
