Coaches usually take one of three roads into/out of London - the M3, the M4 or the M40. I was coming back to London along the last recently and talked about football (soccer to our American visitors) as we passed Wembley and the Battle of Britain as we passed RAF Northolt and between the two I gave a mention to Art Deco architecture as we passed the Hoover Building.

Of all the European capitals, London is arguably the one with the greatest architectural variety, be it residential, commercial or public buildings. What adds to the impression of an incessantly ‘creative kaleidoscope’ is the juxtaposition of old and new, of a mediaeval church next to a 21st century glass building or a Roman ruin in the middle of a 1970s Brutalist development.
