Correction -

"Silbaby is lower than Silbury obviously - but what about Silbury 2? Would the Sanctuary and the top of SILBABY and the top of Silbury 2 all be in a line? Not a two dimentional exact alignment but a three dimensional one....

We would need an accurate height of Silbaby to check that .
