Double chamber lock Kachlet

When it was built in the 1920s, the Kachlet Danube barrage, consisting of a weir, powerhouse and locks, was the largest inland navigation lock in Europe, with an effective length of 230 m and two lock chambers with a maximum rise of almost 10 metres. After nearly a century of operation, a complete refurbishment of the double chamber lock began in 2011 with the extensive dismantling of the old structures and construction of new, separate supporting structures for the lock gates and chamber walls.
