Brent Knoll.....
Brent Knoll has seen human settlement since at least the Bronze Age. It is the site of an Iron Age hill fort, with multiple ramparts (multivallate) following the contours of the hill, broken only by the main entrance on the eastern side.
Before the Somerset Levels were drained, Brent Knoll was an island, known as the Isle (or Mount) of Frogs, that provided a safe 137 metres (449 ft) high haven from the water and marshes. According to legend, Ider son of Nuth, who was one of King Arthur's knights, came to the Mount of Frogs on a quest to slay three giants who lived there. The fort has been claimed as the site of Mons Badonicus.
