The much mutilated earthwork remains of an early medieval ringwork are interpreted as the site of Rugemont Castle. Much of the site has been destroyed by the construction of the Round House in C19 (PastScape)

To the east of Brogborough Park Farm well-defined earthworks consisting of mound, fosse and outworks mark the site of RUGEMONT CASTLE. This castle was the stronghold of the de Greys and their predecessors the Wahulls in this parish, but no mention of it has been found before C12. In 1276 Walter Beywin is described as holding 7 selions 'above the castle of Rugemont.' Extents of Brogborough Manor, to which it appears to have been attached, contain no mention of it, though it may have been the 'capital messuage' found in earlier accounts of the manor. Cromwell is said to have slept at Brogborough during the Civil War and to have made use of the entrenchments to repulse an attack of the Royalist troops." (VCH Vol. 3)

Gatehouse Comments

Identified with Segenhoe mentioned in late C12. Has been very damaged and has been dismissed as a quarry but is scheduled as a ringwork. An alternative site for the recorded Rugemunt Castle is Castle Hill but this has been dismissed as it was on common land. Although now a seemingly isolated site it may have been the focus for the now lost manor of Brogborough (a place-name that may be suggestive of an pre-Conquest fortified site)
