Uhlenburg is the site (Burgstall) of a lowland castle that was built in the 14th century close to the River Aller near Essel in the German state of Lower Saxony.
This Late Middle Ages aristocratic seat only existed for a few decades towards the end of the 14th century and was destroyed by force in 1393/94.
On the eastern side of the motte is a flat depression on an area of 11 x 20 m. An embankment runs from here across the ditch, so it can be assumed that this was the entrance.
The whole castle site is surrounding by a narrow stretch of water, which in the west and north could have been a loop in the old course of the Aller.
This included physical inspections of the site, a magnetic survey, ground resistance measurements and aerial photography.
The historic monument can be reserved for future research as the conditions in the wet valley of the Aller are ideal for its preservation.
Presumably the dukes were attacking the local nobility in order to extend their territory and gain control over the toll sites on the Aller.
The project was supported by the European aid programme LEADER+, because it had located castle sites in the Aller-Leine Valley area.
