Maiden Castle Hill Fort
GPS location 50-41-49 N, 002-28-09 W, south of Dorchester, England.
It is very difficult for a 2 dimensional picture to do justice to a 3 dimensional situation.
The hill fort was begun about 500 BC, and occupied for 900 years or more.
It is protected by 4 high and steep ramparts, which must have been even more formidable before 2000 years of erosion.
Maiden Castle is the largest hill fort in Europe.
There are only a few ruins of buildings, and they may be from the later Roman period.
