The area continued to be inhabited during the Bronze Age, when the population supported itself largely by hunting and fishing in the surrounding marshes, living on artificial islands connected by wooden causeways on wooden piles. There have been many finds of metalwork during peat cutting, which may have been devotional offerings. Brent Knoll has been settled by people since at least the Bronze Age. It is the site of an Iron Age hill fort known as Brent Knoll Camp, with multiple ramparts (multivallate) following the contours of the hill. Several settlements and hill forts were built on the natural islands of slightly raised land, including Brent Knoll, Glastonbury, and the low range of the Polden Hills. According to legend Ider son of Nuth, who was one of King Arthur's knights, went to the Mount of Frogs on a quest to slay three giants who lived there. The fort has been claimed as the site of the Battle of Mons Badonicus.
