 An Iron Age hillfort on Auchterhouse Hill occupies a naturally defensible position, and is protected to the east and south east by a set of five ramparts and ditches.Souterrains, thought to have provided storage space for foodstuffs, were discovered in the 18th century near Auchterhouse Mansion and in Kirkton of Auchterhouse, and aerial photography has since revealed further sites at East Adamston, Bonnyton, Burnhead of Auchterhouse and Quarry House.Long cists, slab-lined graves in which fully extended bodies were placed, are commonly associated with the period between 1000 BC and 500 AD, and have been recorded at Auchterhouse Park, Leoch and Templeton.
