Charles Close Society Lectures



A comparison between the Ordnance Survey and HistoricTownsTrust maps of Cambridge

The Charles Close Society for the study of Ordnance Survey maps is hosting online talks by the Historic Towns Trust’s Honorary Vice-President and former Chair, Professor Keith Lilley, our Cartographic editor Giles Darkes, and Professor Peter Vujakovic, one of our partners in developing educational outreach activities using our maps.


Keith’s talk, on 23 April at 7.30,  is entitled ‘Beneath the lines: mapping medieval townscapes using large scale OS maps’.  He will show how these 19th- and 20th-century maps can be used to locate and identify features from the distant past – as indeed the Historic Towns Trust does.

To attend Keith’s talk, please email chairman@charlesclosesociety.org by April 19 for the Zoom invitation and passcode.


On 16 July at 7.30, Giles Darkes will talk about 'Turning an OS into history: publishing a Town & City Historical Map’.

On 20 August, Peter Vujakovic will talk on the subject ‘Catch Them Young! Introducing children to meaningful mapwork’.

For these talks, please email chairman@charlesclosesociety.org nearer the time.
