Ingleborough hill-fort is an iron - age fortification constructed by the British north-western tribe, the Brigantes. It is very probable that it was built during the first century AD, when the area was under attack from the Romans who were determined to subject the area to their rule.

The fort is situated on the summit of Ingleborough: a flat plateau, having an area of about 15 acres, 2,350 ft above sea level.

Around the top of the summit, the Brigantes built a 3000ft long stone rampart out of millstone grit, which has now collapsed. There were three entrances in the northern, eastern and south-western sides of the wall. Within this enclosure are the remains of the foundations of a number of circular stone huts usually with south facing entrances.

Ingleborough hill - fort is particularly interesting as it was a fortified village rather than a structure built for purely military reasons. It is the only one of its type in Yorkshire. Unfortunately, much of the site has been damaged by ignorant walkers who have taken stones from the ancient remains to build a very uninteresting cairn.
