Weser Lock Minden

The Minden Weser Lock is an economy lock at the Minden waterway junction. It supplements the Minden shaft lock, which is too small for large motor freight vessels. The port of Bremen has also gained direct access to the Mittelland Canal via this larger lock for this type of ship. The new lock is located to the east, parallel to the shaft lock. The architectural design, with its functional style, does not incorporate any elements of the old shaft lock. Towers at the lower head are not necessary because the new lock has a stem gate against the downstream water (pull segment gate against the upstream water). The old shaft lock has these towers because the counterweights of the lifting gate are located there.

In any case worth seeing. The technology on the waterways in Minden is impressive in many ways.

Very beautiful historic building ensemble at the Wasserkreuz near Minden.
