This is the stuff nightmares are made of. Good nightmares. A perverse Aladdin's cave of treasure and artefacts.

One of my favourite things about London is the underground transport system itself. I love the design of the information systems and the stations have so much history — some of them dating right back to the 1800s.

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.

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.

Although freedom of speech is a human right in most civilised countries, Speakers’ Corner has been described as one of the few places in the world where anyone can just climb on a ‘soapbox’ and speak their minds on any subject as long as the police considers it lawful – and almost be guaranteed an audience. It has been like this ever since this area of London’s Hyde Park was the site of Tyburn gallows, where public executions took place between 1196 and 1783, and the condemned were allowed to speak before being hanged. Over the centuries, Speakers’ Corner has been the site of riots, demonstrations, public meetings of groups – such as the communists – that weren’t allowed to gather anywhere else, and was frequented by Marx, Lenin, George Orwell and many other historic figures.  While today it is mainly the scene of eccentrics, religious fanatics and oddballs of all kinds, several prominent speakers such as Heiko Khoo and Jonathan Fitter keep the tradition of meaningful discussions around political and social themes alive. Religion has been debated in Hyde Park since the right to meet and speak freely was formally established in 1872. Today it’s the dominant topic by far, with religious speakers and preachers drawing the biggest crowds and clearly outnumbering the political meetings.  I have been documenting the people gathering here every Sunday since 2012.
