Hi all, the following link takes any and all interested parties to a downloadable book on astronomical heritage sites. The book covers arguably all eras, cultures, and areas and is most assuredly a credible scientific document.
If however the moderator(s) feel this is more appropriate in another forum then please feel free to relocate it.
