Ardrossan Castle, built in four phases, sits high atop Castle Hill, with views of the surrounding coast and countryside. The original castle, built around the late 13th century mainly from grey sandstone, consisted of a simple rectangular shape approximately 70-foot square, with a forward projecting gatehouse which was both keep and main residential block with underground cellars, backed by a walled courtyard. The castle sat at a height of just 50 feet, due to the higher sea at the time, with the modern town of Ardrossan sitting on 'reclaimed' ground. In the early 14th century the gatehouse was rebuilt from the first floor up. Now consisting of three floors, a straight stairway built into the north wall, ran from the first floor to the battlement walk which had a turret at the north-west side of the castle. Following the death of Godfrey de Ardrossan in 1357, without a male heir, the lands of Ardrossan passed through marriage into the Eglinton family. About 1360, Elizabeth, sole heir of Sir Hew de Eglinton of Eglinton married Sir John Montgomerie of Eaglesham and the lands of both Eglinton and Ardrossan passed into the Montgomerie family. During the third phase, occurring in the mid to late 15th century, Ardrossan castle underwent an extensive rebuilt to improve both the living conditions and the castle defences. A large window was inserted in the western portion of the first floor looking northwards and an additional floor was added raising the height of the keep. A variety of buildings along with a chapel were built along the western and north-west curtain walls. A rectangular tower was added at the south-west corner and two long narrow slits, potentially gun ports, were inserted along the south wall. Little was changed during the final phase except for the original entrance to the keep being blocked up and a wide mouthed gun port being added. During the mid-17th century Ardrossan castle was destroyed, allegedly by Oliver Cromwell’s troops. The castle which had been a stronghold for centuries could not withstand artillery fire and was never rebuilt.

Standing on a ridge, Craigie Castle consists of the ruins of a 13th-century groin-vaulted hall house and later castle. The hall house was vaulted in the 15th century, and remodelled into a tower house with ranges of outbuildings. The castle had two courtyards, and was defended by ditches. The lands were held by a Walter Hose around 1150, but the original castle was probably built by the Lindsay family between 1230-40. The property was held by the Craigies when it passed by marriage to the Wallaces of Riccarton in 1371, who had Blind Harry collect together stories and compile a poem about William Wallace, the famous freedom fighter. William Wallace of Craigie is on record in 1464. The castle was abandoned about 1600 when the Wallaces moved to Newton upon Ayr (Newton Castle and Craigie House). Hugh Wallace of Craigie was made a baronet of Nova Scotia in 1669. The property passed by marriage to the Dunlops and was sold in 1783.
