I have vague memories of going up and down those steps in the early '80s. On subsequent visits we took the lift - the stairs were so much better, unless of course you are going to the top - ideally at night.

I used to train on the stairs inside our so called town house in Suffolk - a typical session was walking up/down 40 flights with a 14.8 kg pack; and then 100 flights running without the pack - the total session took about 34 minutes. The 5 storey car park offered similar opportunities, but without the back pack.
