Hellenburg Castle was probably built around 1300. After some renovations and additions, which took place in the 14th and 15th century, the castle got its final shape in 1450. The castle was lost as a result of a flooding caused by a storm disaster in 1477. In the 17th century nothing more remained than a ruin. These ruins were demolished in the 18th century, its stones used as building materials by the villagers of Baarland and the location of the castle was forgotten. The ruins were found accidentally in 1957. Today the foundations have been reserved.
