The earliest castles in Mearns were wooden and it is believed that one was sited at Kirkhill and one at Robshill. No trace is to be found of these castles and the evidence of their existence is to be found only  in folk lore.

Similarly there is little evidence of later stone castles, which local feudal lords would have built on their land. Two castles,however, survived into the latter part of the twentieth century and one is still standing today.
