So is that an indication that the enclosure would've been built around the pond rather than the pond created later. Could raised ditch circles be an early dew pond/rainwater trap design??
Isn't it the case that lot of what are categorized as hillforts aren't defensive...or weren't originally defensive....but used as a basis for a defence by later residents...so what does that mean their original purpose was?
Surely "defensive" doesn't have to mean against warring factions...why not just defence against the elements or loss of livestock???
