The formal gardens are protected as a category A listed building, and are including on the Inventory of Gardens and Designed Landscapes in Scotland.The tower house and mansion are both category B listed.The lands of Drummond were the property of the Drummond family from the 14th century, and the original tower house was built over several years by John Drummond, 1st Lord Drummond of Cargill, from about 1490. In 1605 the 4th Lord Drummond was created Earl of Perth, and added to the castle. John Drummond, 2nd Earl of Perth, laid out the first terraced garden around the castle in the 1630s..
