One time I went to London I took a pre WWII tourist guidebook. Quite fun to find the stuff that survived. There is some really wacky stuff to seak out. like 'The monument.' or the 'guildhall.' Even the foundations of Shakespeare theaters. (under the buttresses of Southwerk bridge.) Can one still find the 'London stone?' Or visit Jeremy Bentham at the University College, London. (by his will they have to show him when asked.)
The good news is I was going to recommend Greenwich. I took a day trip to there. Excuse to meet with one of the curators who stood me up, so I wound up waiting for hours in the back offices. Still there is a lot what can be seen in the Museums. I would nip in and out waiting to see if he had returned.
When I put map Croyden to Greenwich into giggle it shows they are on the same side sort of of the Thames river watershed. Just remember that to the locals 100 years is like 100 miles to Americans, both are definitions of 'short intervals.'
