Knock Jargon is a Iron Age cairn and fort located in Ayrshire, Scotland, and protected as a scheduled monument by Historic Environment Scotland. The site occupies bedrock composed of Dinantian extrusive rocks—mafic lava and tuff formed during the Mississippian period—which provided a naturally defensible foundation for Iron Age settlement. The volcanic geology of the location would have offered both practical advantages for construction and symbolic significance in the landscape of prehistoric Ayrshire.
The monument represents a significant phase of Iron Age fortification in south-west Scotland, when communities constructed defended settlements combining cairn burial structures with fortified enclosures. The combination of cairn and fort at Knock Jargon suggests a site of importance, potentially serving both ceremonial and defensive functions during the Iron Age period.
Today, Knock Jargon remains an important archaeological record of Iron Age settlement patterns in Ayrshire. Its protection by Historic Environment Scotland acknowledges the site's significance for understanding prehistoric occupation and the development of fortified communities in south-west Scotland during the Iron Age.
