[2] The castle comprised a rectangular enclosure, approximately 21 metres (69 ft) on a side, with round corner towers,[1] overlooking the Fithie Burn.

The castle was reported as being ruined by 1682, although the remaining east and south walls were later incorporated into the stable block of Ballumbie House.

Excavations carried out by SUAT Ltd in 2006 ahead of routine land-stripping for a new housing project uncovered burials associated with a stone building.

The excavation revealed a simple rectangular stone building measuring 14 by 4 metres (46 by 13 ft), with both internal burials and an external graveyard.

This family are recorded as the feudal owners of Ballumbie during the 12th century and they may have been the beneficiaries of a Norman-style plantation of new overlords by King David I.

[6] Excavations also revealed a previously unknown, Christian long cist cemetery, underlying the medieval church buildings, containing the remains of several adults and children.
