To the west of the Caterthuns there are numerous scattered cairns and traces of ancient field systems, and a mile or so north of the Kirkton is a group of mounds traditionally thought to be the burial places of Picts or Danes.
Surviving from the Pictish period, the five Menmuir Stones, presently housed in the Pictavia Centre near Brechin, were found in the kirkyard of Menmuir. They are decorated with key pattern and interlaced designs, and carved with figures of riders, hunting scenes, real and imagined animals, and Christian crosses. An ancient cup-marked stone has recently been found in the area.
In the Middle Ages most of
Menmuir was covered by the royal hunting forest of Kilgarie, still the
name of a local farm. A rare survival of a medieval deer-dyke, probably
the eastern boundary of the Kilgarie forest, runs from the south bank of
the West Water and climbs between the Brown Caterthun and the Hill of Lundie
(NO 558 677) and continues down to Cairndrum. The title deeds of some local
farms still specify their location "within the Forest of Kilgarie".
