The Freyburg lock is a listed lock on a lock canal of the Unstrut in Freyburg (Unstrut) in the Burgenland district in Saxony-Anhalt in the center of the Saale-Unstrut wine-growing region . The city belongs to the Unstruttal community , whose administrative seat it is at the same time. The lock is registered under registration number 107 05062 of the State Office for the Preservation of Monuments of Saxony-Anhalt .
history
The use of the Unstrut as a transport route has been documented since 981. Shipping on the Unstrut is mentioned in 1602. For a long time, economic use worth mentioning was only possible to a very limited extent due to the shallow depth and the muddy banks. Great efforts had to be made to maintain the riverside paths, as these were indispensable for towing the barges. From 1790, shipping on the Saale was expanded further. The Elector of Saxony, Friedrich August III. In this context, ordered that the upper Saale and the Unstrut be made economically navigable. The Freyburg lock, formerly also known as the Freiburg lock , was built between 1790 and 1794 as part of a major project to make navigable from the Saale to the Unstrut. It was completed in 1794 as one of the original 12 Unstrut locks. In 1834 the Unstrut was made passable throughout (quote) , and 12 locks are built on it, namely to Artern, Ritheburg, Schönewerda, Roßleben, Wendelstein, Nebra, Vitzenburg, Karsdorf, Burgscheidungen, Laucha, Zscheiplitz and Freiburg. All locks have drawbridges so that the roads are not interrupted.
In the mid-1950s, the Unstrut lost its economic importance as a waterway. The hydraulic structures were neglected and part of the weir in the Unstrut broke through in 1966. In 1967 the river was deleted from the list of inland waterways in the GDR and the Artern, Schönewerda, Roßleben, Nebra, Vitzenburg, Karsdorf and Freyburg locks were shut down as part of a flood protection program for the Unstrut. As part of another river engineering project, the weir was completely demolished in 1971 and a temporary dam was built in 1977. The lock was covered with earth about one meter high. In 1989, planning began for a new weir and a reconstruction of the lock system, which was then exposed in 1992. In June 1993 construction work to restore the lock was officially started. The inauguration of the Freyburg lock took place on November 27, 1995. The small passenger ship Fröhliche Dörte was the first ship in decades to pass the lock.
description
Today's Freyburg lock is a chamber lock with straight chamber walls made of Nebra sandstone . The lock has a usable length of 50.67 meters. It is 5.65 meters wide. A second sub-head was probably built in 1878 during major repairs. To close the lock chamber, stem gates are used, which are opened and closed via gate poles and a mechanical drive. The lock was previously approved for ships up to a length of about 46 meters, which corresponds to the unstrut dimensions that are no longer in use today . The entire dam consists of the weir, the sluice and a fish pass. The weir and the fish pass were rebuilt from November 1994 to October 1995. The weir system consists of a fixed weir with a width of 80 m. With the reconstruction and recommissioning of the weir and the lock in Freyburg, a new fish pass was built at the same time, which is supposed to enable the passage of the unstrut at this transverse structure for migrating fish species and invertebrate organisms. This is a basin pass at the weir in Freyburg .
Since the river is no longer a federal waterway here , tourist use is in the foreground. Smaller passenger ships and water sports enthusiasts with smaller boats and shallow drafts can still navigate the Unstrut.
Responsibility for the Unstrut from km 0.00 to 45.28 is exercised by the Sangerhausen river area in the State Office for Flood Protection and Water Management Saxony-Anhalt (LHW) Saxony-Anhalt, based in Oberröblingen .
