Time Out says
During the first weekend of October, people all over the country are getting together in the name of art and science and setting up temporary Fun Palaces. The campaign is based on an idea conceived by the late theatre director Joan Littlewood and architect Cedric Price in 1961 to create a 'labratory of fun' for children and adults alike; a place where people could get creative, learn to do something or watch someone else doing it. For its fifth year, already 40 palaces have been planned to pop up across London. To find a Fun Palace near you, visit funpalaces.co.uk/discover.
