I live quite close to Salisbury and have no idea apart from "bloody tall", how high the spire thrusts skywards. Apart from anything else we'd generally measure it in feet.
I'd better spell it out: One of the gentlemen accused of poisoning a Russian ex-pat in Salisbury (Hants. UK) claimed that he was a tourist and came to see the cathedral in Salisbury. He quoted the height of it to quite a degree of accuracy as proof of his touristic intentions. He really did not smear novichok on Mr Skripal's door.
