The Somerset levels from Brent Knoll
Brent Knoll (449 feet) has seen human settlement since at least the Bronze Age. Brent Knoll Camp was an Iron Age hill fort, with multiple ramparts 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 Mount of Frogs, that provided a safe 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.
