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.
