Briare Canal
Loiret, France
The Briare Canal (Canal de Briare, pronounced [kanal də bʁijaʁ]) is one of the oldest canals in France. Its construction started in 1604. It was the first summit level canal in Europe that was built using pound locks, connecting the Rhone-Saône and Seine valleys. It is 57 kilometres (35 miles) long and is part of the Bourbonnais route from Saint-Mammès on the Seine to Chalon-sur-Saône on the Saône. From Briare to Buges, the canal rises through the first 12 locks some 41 m (135 ft) and then falls 85 m (279 ft) through the remaining 24 locks.
