People often talk of the Hollywood Hills but it's rare to hear the City of London talked about in terms of its hills - but a city of two hills it originally was.
I was reading about this in Discovering Roman London (Grace Derwent 1968) just now in the pub, the words somehow reaching my brain through some of the worst karaoke singing I've ever been subjected to. You can see the legacy of the London hills recorded in the street names of the City - some of these are in the book and then I've sat here looking for more: Cornhill and Ludgate Hill (the twin hills), Bennet's Hill, Huggin Hill, Garlick Hill, Dowgate Hill, Fish Street Hill, St. Mary at Hill, Dunstan's Hill, White Lion Hill, Addle Hill, Lambeth Hill, College Hill, and obviously Tower Hill. To the west you find: Saffron Hill, Back Hill, Herbal Hill, Eyre Street Hill, Vine Hill, Snow Hill.
Derwent gives us this guide to the scale of the incline on the western slopes:
"To get an idea of what the slope up from the floor of the valley to the western hill of the twin hills was like, try walking up the steps from Farringdon Road to the top of the Holborn Viaduct, or even look over the viaduct and see how far it is above the traffic beneath." (p.21)
