The James Hamilton Heritage Park is a park primarily containing a manmade loch with watersports facilities and surrounding nature sanctuary. It is overlooked by Mains Castle, a privately owned tower house and former seat of the Lordship of Kilbride. The castle is situated beside the Laigh Mains Motte, the predecessor site of the early stronghold of Kilbride built by the Valloines family and later occupied by the Comyns, before it was confiscated by Robert the Bruce and later came into the possession of the Lindsays.
