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.

My walk through the Heath often continues on to the Camden Arts Centre, a really fantastic exhibition space that runs workshops and courses as well as having a great café and bookshop to boot. I collect their exhibition booklets called File Notes - beautifully designed by James Goggin and Sarah De Bondt - some memorable shows include Eva Hesse Studiowork, The Bruce Lacey Experience and Serena Korda’s Aping the Beast. The latter concluded with a procession from the gallery up to the Heath, culminating in a re-enactment of The Battle of the River Plate in a pond. This is my photo of the Beast and the Boob Meteorite.

The most beautiful contemporary gallery in London aptly named White Cube, the space is an artwork in itself. Its portfolio of artists and exhibition programme is top of the league, always presented as with style and grace as the space itself. Photograph by Paul Riddle

I probably spend too much time here but I love it for the atmosphere. During the day it’s quite empty. The proprietor is often dozing in the back corner and you can read for hours with just one cup of tea without anyone bothering you. It picks up in the evenings as all the regulars pile in with pre-bought bottles of wine.

I felt in love with the giant glasshouse, it's a great place to draw.
