The Lauenburg castle ruins were a two-part hilltop castle and are located on the castle hill above Stecklenberg.

The castle complex was first mentioned in a document in 1164 and was probably built over a period of ten years. It consists of the approx. 200 m long „Great Lauenburg“ and the approx. 50 m long „Small Lauenburg“, which is to be regarded as the outer bailey. It was once the largest castle complex in the Harz region, a Salian imperial castle which, like the Harzburg, was probably built under HEINRICH IV (1050–1106). In 1165 it went to HEINRICH THE LION, who had to hand it back to Barbarossa in 1180. In 1267, it was taken over by the Margrave of Brandenburg and given as a fief to the Counts of Regenstein until it was finally conquered and restored under the Bishop of Halberstadt, ALBRECHT III (1366–1390). After its later use as a quarry, it fell into Prussian state ownership in 1897.
From the observation tower of the outer bailey, you have a beautiful view of the Devil’s Wall near Weddersleben and the Harz foreland. The stamp box is located next to the information board below the outer bailey.
