Silbury Mound

Suggest we hang fire on a permanent name until the original name is discovered (there may be important information embedded in the original name).

The only original name that's com up, the Great Bank, is encouraging in a way as it's so clearly a misidentification. It's definitely not a bank, as it's round and is clearly a mound.
I'm wondering whether the name Great Bank actually refers to what it's built up against, which is self-evidently a bank.
