There is a thing that the welsh do,that is very similar.there is a modern group of people,who have created a thing called the eisteddfod,and claim it is an ancient druid thing that has been discovered and re-created as it originally was in the ancient past.the thing they do,is hold a big gathering,and built a fake stone circles all over wales,wherever the eisteddfod has taken place.the crafty thing is,as time goes by,and the eisteddfod event is forgotten,the local town/village folk,promote the stone circles as original ancient stone circles.
Here are a couple of pictures of a modern 1951 built stone circle in a town called llanrwst.I grew up in this area,and no one knew there had been an eisteddfod held there,only,that there was an ancient stone circle,built thousands of years ago by mysterious druids.
Here is a link to a wiki entry,that lists all welsh towns that have a fake modern stone circle,created for the eisteddfod meetings.
