If you have any interest in Whitechapel, take a look at this magnificent web site. Histories of Whitechapel maps the area in unprecedented detail.
The zoomable map allows you to click on any building in central Whitechapel, where you'll find information on the building's age, function and history. The more important buildings carry detailed histories, often with video footage, archive material and — crucially — the memories of people who worked and lived in the area.
And that's the crux of the site. Its makers are looking to crowdsource 'memories, photographs, drawings and film' from anyone who cares to share their affection for the area.
If successful, the concept could be expanded to other areas of town.
Histories of Whitechapel is put together by The Survey of London, built by The Bartlett's Centre for Advanced Spatial Analysis (CASA), and is supported by the Arts and Humanities Research Council (AHRC). Have a play and, if you can, contribute some memories.
