When I visited Stonehenge, there were neo-druids conducting a ceremony there. 
Interestingly, Stonehenge has nothing to do with the original Druids. Stonehenge predates them, by quite a bit. Moreover, from what we know of actual ancient Druidic ceremonies, they were generally conducted in woodlands, not in stone ceremonial spaces. 
So why the association of Druids with Stonehenge? Apparently, this dates back to the late 18th early 19th century, when antiquarian interest in Stonehenge really got going in England, at the same time as antiquarian interest in pre-Christian religions, and Druidism in particular. It was simply assumed that the Druids must have built Stonehenge. 
The actual age of Stonehenge was only determined much later, well after the association between Druids and Stonehenge was already well established in the popular mind. >

I mean "neo-druids" have nothing to do with any sort of ancient traditions. It's a completely modern invention. >

Kind of like Wicca. I had this friend once who fancied herself a proper witch and bought all this stuff ‘required’ for casting ‘spells’ from some Wiccan book she had. I didn’t judge her or anything for it, to each their own. But when I showed her (gently and respectfully) that Wicca literally did not exist until the 1940s she got real quiet. Then angry. Some people just feel better about things and their life in general if they convince themselves that they have some level of control over the material and spiritual worlds because hey it’s pretty easy to feel that everything is completely out of your control. Because it is. And all the daggers, candles, potions, and grimoires in the world ain’t gonna change that. >

You’re right about Wicca. Whole deal started when a dude named Gerald Gardner decided to speak openly about what he called Wicca when the laws against witchcraft were repealed in England. There is zero evidence that Wicca is any older than that, despite claims. That said dude was involved in several occult orders and individuals. 
Something doesn’t have to be old to be valid. I’ve been in the neopagan community since the early 90s, and I know many who are older than me who’ve been involved since the 60s. Most folks I know wouldn’t call themselves Wiccans, but Wicca certainly helped kick off the modern neopagan movement.  The concept of nature based spirituality and a broader concept of divinity is what many folks feel they need, and imo their ain’t anything wrong with that. 
Btw. There’s been various groups calling themselves’ Druids’ since the Victorian era. The oldest still running is Ancient Order of Druids, founded in 1781. It started off more like a frat with ceremonial trappings, not unlike freemasonry, though unrelated.  It does not classify itself as a religious org, but it did have some influence on modern druidry (long story with excessive englishess).  Nearly all the modern Druid groups I can think of that are of a spiritual nature got created or revived (depending on your pov) as early as the 60, and the founders all had some flavor of occult in their background. 
Eh.. anyway. It’s a very convoluted historical mess and there’s a lot of bad scholarship and misinformation to weed through.  It’s not a wonder people may be misinformed. >

Did that yesterday, Seafood and champagne. Never really understood why it's such a big thing with midsummer. Winter solstice is the real celebration. >

I donno atleast in Latvia midsummer is huge we even get holidays for those dates >

Same in Sweden, unofficial national day. 
Honestly I’m not against it, I’d embrace any holiday. >

Ditto. Queen Victoria died 121 years ago and Im looking forward to golfing on the holiday we get annually on her birthday. >

When other people see issues with migration I see possibilities. Imagine adopting more holidays. I’d gladly throw paint on people or tomatoes for that sake.
