Pöhlde Castle

The Pöhlde Hillfort, also known as King Henry's Birding Ground, is a historic fortification on the Rotenberg hill near Pöhlde. This complex, consisting of a larger outer bailey and a smaller main castle, served as a refuge castle.
History+
Archaeological investigations suggest that the Pöhlde Hillfort was sporadically used as a refuge castle between the 9th and 12th centuries. The site was strategically located on the Fastweg, a military and trade route, which indicates its function as a road block. The older part is the oval outer bailey, which occupies most of the ridge and featured a rampart with a ditch. Later, the almost circular main castle was inserted into the western area of the outer bailey. A pincer gate stood between the two parts of the castle. Excavations in 1934, 1951, and from 1955 to 1974 unearthed pottery shards from the 9th and 10th centuries, as well as wood remains, allowing the outer bailey to be dated between 750 and 1100.
