Ecluses de Fonserannes at Beziers
A flight of eight canal locks at Béziers, just before the last stretch of the canal meets the Mediterranean. This staircase allows a 21.5 metre drop in in a distance of 300 metres. It's a slow process in practice. The Ecluses at Béziers are the third most popular tourist site in the Languedoc, after the cité de Carcassonne and Pont du Gard.
