Hampshire is a county in Southern England with some notable archaeology and many notable historic buildings. The chalk downland of the South Downs and southern edges of Salisbury Plain were settled in the neolithic, and these settlers built hill forts such as Winklebury and may have farmed the valleys of Hampshire. Hampshire was part of an Ancient British kingdom the Celts called Gwent (not be confused with the county in Wales) or Y Went, which also covered areas that would later belong to Somerset and Wiltshire). In the Roman invasion of Britain, Hampshire was one of the first areas to fall to the invading forces.
