Hill forts developed in the Late Bronze and Early Iron Age, roughly the start of the first millennium BC. The reason for their emergence in Britain, and their purpose, has been a subject of debate. It has been argued that they could have been military sites constructed in response to invasion from continental Europe, sites built by invaders, or a military reaction to social tensions caused by an increasing population and consequent pressure on agriculture. The dominant view since the 1960s has been that the increasing use of iron led to social changes in Britain. Deposits of iron ore were located in different places to the tin and copper ore necessary to make bronze, and as a result trading patterns shifted and the old elites lost their economic and social status. Power passed into the hands of a new group of people. Archaeologist Barry Cunliffe believes that population increase still played a role and has stated " provided defensive possibilities for the community at those times when the stress burst out into open warfare. But I wouldn't see them as having been built because there was a state of war. They would be functional as defensive strongholds when there were tensions and undoubtedly some of them were attacked and destroyed, but this was not the only, or even the most significant, factor in their construction".
Description
The hill fort, which is approximately, and in height, covering, consists of a fairly large flat open area, roughly triangular in shape, that has been fortified by ramparts and shaping of the steep-sided hilltop around the northern, eastern and southwestern sides of the hill. It rises to an altitude of above sea level, and provides views over the lands it would have once commanded. From here, there are clear views north to Bristol, east to Bath and the Cotswold Hills, and south over Stanton Drew stone circles to Chew Valley Lake and the Mendip Hills. The underlying rocks are Inferior Oolite of the Jurassic period.
History
It is believed to have been built, around 250 BC, by the Dobuni who were one of the Celtic tribes living in the British Isles prior to the Roman invasion of Britain. The name Maes Knoll is derived from the Brythonic word maes meaning flat top, derived from Latinmensa meaning table., and Old English knoll or knowle meaning hill. The existing scarp slopes were steepened and, on the north-western edge of the fort is an earthen mound, known as Maes Knoll Tump, about above the rests of the fort defences, which is across and above a defensive ditch. The later Wansdyke runs west from it along the north side of Dundry Hill and south-east from it. During the Second World War, a draughty, rectangular, corrugated-iron hut on the top of the tump sheltered Dundry Home Guard soldiers, allowing them to watch for enemy aircraft and potential parachute or glider invasions of Bristol. The flat plateau immediately to the east of Maes Knoll tump had perhaps 50 stone cairns to deter enemy glider landings.
