A treasure trove in the The City of London. The Archive of London. Strongrooms hold kilometres of shelving; boxes of matter that has somehow been catalogued and categorised in a traceable manner by the public, for academic, genealogical and other research. This beautiful book is from a box on Epping Forest. On the same visit, I looked through photographs of Blitz singsongs in Bethnal Green Underground station, 1980s anti-Thatcher / pro-GLC gig posters and paper concertina optical models of the Crystal Palace.
The Greenwich Observatory with its green laser beam can transfigure any night sky. If you decide to cross the Thames via the foot tunnel, make sure you look out for the green ray. You can be on one side of the meridian in a minute, and cross to the other side on the next, without even realising it.
Arguably the best café in London – or at least East London – with an incredibly welcoming atmosphere, delicious array of food and drinks, and hypnotising views to Broadway Market. Visit early in the mornings, for a roque-monsieur at lunch, or to get lost in their cheese selection at the market stalls on Saturday. Warning: addiction likely to occur.
