This is a list of hillforts on the Isle of Man . Found across Europe and the British Isles, hillforts are a type of prehistoric archaeological site dating to the Bronze Age and Iron Age, and to a lesser extent the post-Roman period. They are classically defined as small hilltop settlements fortified with earthworks, but many are not located on hills, and probably did not function as forts. [1] Their function is unclear; although conventionally interpreted as defensive fortifications [2] and centres of economic political power, [3] there is little evidence that they were ever attacked, [1] and more recent scholarship has suggested that they may be better interpreted as monuments.

According to the Atlas of Hillforts of Britain and Ireland , there are up to twenty eight extant hillforts on Mann itself, and possibly two on the Calf of Man. All but two are on the coast. [5]
