The wonderful world of ruins

Today, I thought it would be a REALLY good idea, as part of 'the great work' to produce a world database and map of the main ruin sites.  How hard could that be?!  My laptop almost reached meltdown by the time I had got to ruin number 189...but I still think eventually it will turn out to be a good idea.  There are ruins everywhere - Pakistan, Sri Lanka, Mexico, Ireland, Thailand, Cambodia... I hope to add my world map to this blog when I have fathomed out how to produce it properly.  I feel an intimate session with ArcGIS coming on...
