Burg Warberg, Medieval castle in Warberg, Germany

Burg Warberg is a castle complex on the eastern edge of the Elm hills in Warberg, Lower Saxony. It is divided into a south-western upper castle and a north-eastern lower castle. The upper castle centres on a nearly square keep with arrow slits, about 8 metres per side and 19 metres high, surrounded by a one-storey building with a decorative portal from the second half of the 16th century. The lower castle courtyard is enclosed by buildings on three sides, including a three-storey stone main house and a chapel first mentioned in 1346.

The castle was founded in the early 13th century by the Warberg family, after an older fortress about a mile (2 kilometers) to the southwest was destroyed in 1199. The new site took over the defensive role of the previous stronghold.

The castle is used today as a training center for farming, hosting courses and conferences that bring together people from rural and agricultural fields. Walking through the grounds, visitors can see how a medieval building has been given a working role in everyday life.

The castle stands in Warberg at the eastern edge of the Elm ridge. The surviving moat sections lie east and west of the complex, and a 38-metre-long outer rampart extends to the southwest. The upper castle is separated from the lower castle by a retaining wall, so expect level changes between the two parts.

The chapel in the upper castle is first recorded in a document from 1346, making it one of the oldest named parts of the whole complex. Its survival shows that religious practice was a regular part of life within the walls, not a rare occasion.
