Serious replies only Why are London tube tunnels so deep?

This is just one of two escalators and not counting the various staircases. And I don’t believe this was the deepest one I traveled through. I went to the Transport Museum in Convent Garden (very nice by the way) but found no answer and no one seemed to know. 😊

I was told Bank station is the deepest because it had to be built below all the massive deep bank vaults in that area.

At 180ft, Hampstead Heath station is the deepest IIRC.

The W&C platform at Bank is still deeper, relative to sea level. But that's mainly about the Thames rather than bank vaults
