As it stood in 1100

What Hen Domen looked like in its prime.

A low, steep-sided earthen motte 8 m high with a flat round summit c.6.7 m across stands in the south-west corner of an oval bailey 50 by 40 metres, surrounded by an oval ditch about 2.7 m deep. At prime the motte bears a tall timber tower linked by a narrow timber bridge to the bailey, whose defences are a continuous wooden palisade enclosing a compact cluster of timber buildings including a small hall, gatehouse and granary.

Its story

The story of Hen Domen.

Hen Domen, Welsh for "old mound", is the site of the original Montgomery Castle, a timber motte-and-bailey built by Roger de Montgomery, first Earl of Shrewsbury, around 1070, after William the Conqueror gave him extensive areas of Shropshire. From 1105 it was the home of the de Boulers (Bowdler) family, and it is from Baldwin de Boulers that Montgomery takes its Welsh name, Trefaldwyn, "the town of Baldwin".

Excavations from the 1960s to the 1990s revealed a grand and complex timber castle: a towering building on the 8-metre-high motte, connected by a bridge to a bailey containing a large hall, along with a wooden palisade on the bailey defences, a wooden tower, a gatehouse, a granary and a possible chapel.

When the castle was rebuilt in stone between 1223 and 1234, it was moved to a rocky promontory a mile to the south-east, the location of the present town of Montgomery, and Hen Domen was left behind. The Old Bell Museum in Montgomery holds permanent exhibitions on both castles, with scale models of each.
