In 1325 Robert I exchanged lands at Cardross for those of Old Montrose in Angus with Sir David Graham. It was to be here that Robert would build the manor house that would serve as his favoured residence during the final years of his reign. The extant chamberlain's accounts for 1328 detail a manor house at Cardross with king's and queen's chambers and glazed windows, a chapel, kitchens, bake- and brew-houses, falcon aviary, medicinal garden, gatehouse, protective moat and a hunting park. There was also a jetty and beaching area for the 'king's coble' (for fishing) alongside the 'king's great ship'.
