Today is the Summer Solstice. I spent a lot of energy in my youth on reading about Stonehenge, including reading a lot of the baloney that is out there.
I thought the following sites were interesting and reliable enough to be included here:
First, the English Heritage website, which has a LOT more thatn just info about Stonehenge, and is a great site to visit to coordinate dates for a visit to the UK, since it has a calendar for events country-wide.
While a little sparse on graphics and heavy in text, Hengeworld is well worth the time it takes to read it. The webmaster is editor of British Archaeology magazine, and so has field-cred.
Next, for general information of all types, About Stonehenge . Info is a slghtly more commercial spot, with links to an ongoing blog, books (Amazon.com...), and tour operators that go to Wiltshire.
For information on the remodeling and the on-going controversy surrounding the A303/A344 highways that cross the site, the Stonehenge Project pages are a good place.
Lastly, there is Stonehenge Laser Scan which has a digital model of the site, from which I took this frame, looking at the Heel Stone from inside the trilithons and the Sarsen Circle:
Of course, I have to also link to Ian Gillian's tale of woe when the rock band Black Sabbath tried a set based on Stonehenge, that ended up beign the origin for Rob Reiner's movie spoof "This is Spinal Tap" and their take on this episode...
