The extended property is located on the Amtshausberg [de], 141 metres (463 ft), and almost 100 metres (330 ft) m above the Weser, with a steep grade to east and south.

The bent river has a natural harbour, on the medieval main road from Frankfurt to Bremen.

Drawings dating back to 1581 are extant, but they are no reliable representation.

The castle ruins were demolished in 1709, with only the dungeon surviving until 1936.

[2] Part of the reconstructed castle is covered by a modern protective roof.
