At Courthill excavations were undertaken by Cochrane–Patrick (1878) & Dobie (1876) in the 1870s. The remains of a timber hall similar to those in England dated to around the 8th century were found. These digs refer to a timber hall or court structure with a turf roof, that was then replaced by a motte (a structure on a hill) similar to those used by the early Normans infiltrating the area then. Amongst the debris a flint arrow head from an even earlier period was found.
