Shortly after the Norman Conquest the conqueror's kinsman Roger de Montgomery, who had been left in Normandy as co-regent with the Duchess, received large tracts of territory both in Sussex and Shropshire and was created Earl of Shrewsbury, where the castle already established by the Conqueror by 1069 became its principal seat. At some date between 1070 and 1074 Roger built a castle in what was the Shropshire hundred of Witentreu which he called after his ancestral fief in Normandy. This was however not on the site of the present castle but was the earthen motte and bailey of Hen Domen one mile north of the town; any reference to Montgomery prior to 1223 refers to this and not the present castle.

On the fall of Hen Domen it was granted by Henry I to Baldwin de Boulers, whose stepson Stephen (slain by Llywelyn ap Madog of Powys in 1152) and grandsons Robert and Baldwin succeeded him. It is presumably from the first or second Baldwin, who died about 1207, that the Welsh name of Trefaldwyn (a mutation from Tre Baldwin) arose.

Hen Domen was not totally abandoned at this date however, for the pottery from the site seems to continue down until at least the end of the 13th century. Unlike the new stone castle which replaced it, Hen Domen commands a direct view of the ford across the Severn and it may have been maintained for many years as an outpost of the new castle.
