Casalecchio lock

The Chiusa di Casalecchio di Reno is the oldest hydraulic system in Europe still in use, used continuously and uninterrupted, in fact for eight hundred years it has governed the waters of the river Reno and through the canal system it has provided the city of Bologna and the entire the Bolognese plain that motive energy that made the territory flourishing.

The lock was built in 1208 and rebuilt in 1567 based on a design by Vignola (Jacopo Barozzi), and still remains a wonderful testimony of the hydraulic engineering of the time.

La Chiusa is located almost in the middle of the course of the Rhine, that is 83 kilometers from the source (which is on Monte delle Piastre, in Pruneta, 900 meters above sea level) and 128 kilometers from Torre di Primaro, where the river flows into the Adriatic .

It is 160.45 m long, on average 35.45 m wide, with a slip of 34.55 m and a drop of 8.25 m.

This hydraulic monument has also assumed a symbolic value of equal strength and importance: at the end of 2010 it was in fact included in the list of the UNESCO 2000-2010 program of the Messenger Heritage of a Culture of Peace for young people.
