This exhibition seeks to address that lack with a combination of specially-commissioned photographs and resin models of Hawksmoor's churches. Apparently simple and even sparse, the exhibition draws visitors in and focuses their attention where it belongs: not on mysterious rites and ley-lines but upon the buildings themselves.
The exhibition has just over a week to run, and if you are near Somerset House, I would recommend a visit. There is more information here; London Historians has also visited.
