Most London Blue Badge Tourist Guides have had clients who want to get a snap of themselves by a red London phone box, often with Big Ben in the background. It is almost a rite of passage for a visitor to London and so the red boxes at the end of Whitehall often have long queues of people waiting outside for the chance to take a picture of themselves. The phone booths are rarely put to their original use – namely, to make phone calls. Now, of course, the mobile phone reigns supreme and most people have a smartphone in their pocket.

Working as a Blue Badge Tourist Guide in I often show my guests – especially if they have young children - the bust of the William Buckland in the south aisle of Westminster Abbey. He may hardly be a household name but Buckland is memorialised for his appointment as Dean of the Abbey in 1845 and his work as an early palaeontologist and undergroundologist (geologist). He excelled at two of the new sciences that would enthral Britain in the nineteenth century.
