Image collection
Since 1995 I have maintained an on-line collection of photographs of archaeological and archaeoastronomical interest. It is intended primarily as a research and reference tool, to be used in conjunction with other information about the sites in question and issues related to their interpretation available in books such as Astronomy in Prehistoric Britain and Ireland. Picture quality is variable but the collection does contain many pictures suitable for re-use in publications.
Leicester University Archive
The original collection of c. 1100 images can still be accessed as an archive held on the Leicester University website.
New developments
Over the last few years I have accumulated several thousand more images of sites both in Europe and in many other parts of the world, and I am working to make a number of these available on-line.
Images previously made available to support Case Studies on the UNESCO–IAU Portal to the Heritage of Astronomy—of sites such as Chankillo in Peru, various seven-stone antas in Portugal and Spain and the Stonehenge area in the United Kingdom—have been temporarily removed as part of a system upgrade but will be back shortly.
