Le Canal du Midi
The Canal du Midi is a 240 km (150 mi) long canal in Southern France (French: le Midi). Originally named the Canal royal en Languedoc (Royal Canal in Languedoc) and renamed by French revolutionaries to Canal du Midi in 1789, the canal is considered one of the greatest construction works of the 17th century.
The canal connects the Garonne to the Étang de Thau on the Mediterranean and, along with the 193 km (120 mi) long Canal de Garonne, forms the Canal des Deux Mers, joining the Atlantic to the Mediterranean.
Strictly speaking, “Canal du Midi” refers to the portion initially constructed from Toulouse to the Mediterranean – the Deux-Mers canal project aimed to link together several sections of navigable waterways to join the Mediterranean and the Atlantic: first the Canal du Midi, then the Garonne which was more or less navigable between Toulouse and Bordeaux, then the Garonne Lateral Canal built later, and finally the Gironde estuary after Bordeaux.
