A hill fort is a type of earthworks used as a fortified refuge or defended settlement, located to exploit a rise in elevation for defensive advantage.Well worth taking time for a look-at.
The fortification usually follows the contours of a hill, consisting of one or more lines of earthworks, with stockades or defensive walls, and external ditches. Hill forts developed in the Late Bronze and Early Iron Age, roughly the start of the first millennium BC, and were in use by the ancient Britons until the Roman conquest. There are around 3,300 structures that can be classed as hillforts or similar “defended enclosures” within Britain, all worthy of considering.
