From the long shelf of books about London that I keep (and keep adding to) the one I most cherish is The London Nobody Knows. Published sixty years ago, it is part whimsical vade mecum, part urban elegy, a book that celebrates the lesser-known nooks and corners of a capital that was in drastic transition. Knocked about by German bombing twenty years earlier, London had then come under sustained assault from planners and developers largely inimical to the architectural quirks and anomalies of the Victorian age. The author, Geoffrey Fletcher (1923–2004), was working against the clock: the ‘tawdry, extravagant and eccentric’ place he loved was fast disappearing, and a recording angel like himself needed his wits about him if he was to preserve its memory. The year of the book’s appearance, 1962, had already seen the destruction of two major landmarks, the Euston Arch and the Coal Exchange. More were bound to follow.
