London Screen Archives
This 30 minute film, made in 1961, can be viewed online at the London Screen Archives. It tells the history of Wood Green from tiny hamlet to major shopping centre told through still photographs and additional materials including maps, paintings, engravings, newspaper advertisements, motion footage. It includes Alexandra Palace, and also covers transport, local industry, the impact of wars and the development of new council estates.
Although the film doesn’t have a soundtrack, the London Screen Archives website has excellent, very detailed accompanying notes, explaining what is seen in the film, along with an essay giving substantial historical background and context. If you are interested in the history of the area, this is really well worth reading.
