This summer the project will be experimenting with methods of transporting stone based on theoretical ideas about how stone was transported from various places on the east coast of Ireland to Newgrange and there are further plans for next year. The film company Crossing the Line Films is involved on the project. They were previously involved in the extremely professional production of Blood of the Irish.
I was involved in a similar project based in Denmark which resulted in the sailing of a reconstructed viking ship called the Sea Stallion from Roskilde to Dublin and back. I can highly recommend it and if I can find the time I might get involved myself.
I'd strongly advise a look at the superb website and encourage people to get involved in a project that represents an exceedingly rare opportunity.
