Dunnideer Castle

Dunnideer Castle, now ruined, was a tower house located near Insch, Aberdeenshire, Scotland. It was built c.1260 partially from the remains of an existing vitrified hill fort in the same location. It consisted of a single rectangular tower of 15m by 12.5m with walls 1.9m thick. Evidence suggests that a first-floor hall existed. Evidence shows it had several floors.
