Alte Schleuse Niegripp, A lock structure in Niegripp in Saxony-Anhalt

The Alte Schleuse Niegripp is a lock on the Niegripper Altkanal in Burg, built with stone and featuring large gates for water control. It was constructed between 1865 and 1872 as part of the Ihlekanal development and allowed ships to navigate changes in water levels.

The lock was built between 1865 and 1872 as part of the Ihlekanal to assist ships navigating varying water levels. Following the expansion of the canal system in subsequent decades and the construction of newer waterways, the old lock was later deactivated and filled with earth.

The lock gave its name to the surrounding waterway: the western end of the Ihlekanal, where it stands, is now called Niegripper Altkanal, and the stretch up to the structure is still a federal waterway listed as Altstrecke Ihlekanal bei Niegripp. Its stem gates were dismantled and an earth wall piled up in the chamber as a closing dike between canal and Elbe. The building is a listed monument.

The old lock lies in the Niegripper Altkanal, the former western end of the Ihlekanal, which is still a federal waterway up to the structure. The chamber is closed off by an earth embankment between canal and Elbe, so through-passage is no longer possible. Approach on foot or by bike along the Altkanal; the site is a listed building, so stay on the paths and do not climb the embankment.

The chamber's stem gates were dismantled and an earthen wall piled up inside as a closing dike between canal and Elbe. The old canal remains navigable and is still a federal waterway, listed as Altstrecke Ihlekanal bei Niegripp. The lock itself is a protected monument.
