The Ecclesiological Society
A society going back to 1839 which studies churches. With the enormous number of dials on church property, there is an obvious overlap.

The Society for the History of Astronomy, founded in June 2002 as the UK's national society specialising in the history of that great science. The Society's Survey of the Astronomical Geography of the UK is already shedding light on the undiscovered local history of astronomy in all regions and at all levels.
