I vaguely thought about leaving London recently and the British Library came to mind as somewhere I’d miss. It’s an essential resource because it has almost everything. It also has some interesting exhibitions.

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.

Aside from the fact of the underground being the oldest running railway system in the world, I find the underground just an incredibly strange place. Sometimes it’s like I’ve entered an organised maze and just walk without even thinking. The photo is taken of the floor from one of the trains, it’s normally what you tend you look at when you’re on the train.

Paul Rothe n Son has been there 120 years, bang in the middle of town. Hard to find a proper old-school deli in central London nowadays, n none more proper than this place. Great jacket potatoes, soup, sandwiches. It looks the part too. And the service is always great. Try and avoid the lunch queue.

Designed by Wells Coates, the Isokon Building opened in 1934 and was the first apartment block to be built using reinforced concrete. The Isokon Gallery is open at weekends telling the story of the Isokon building, the pioneering modern apartment block as an experiment in new ways of urban living.
