Watch Cadw's CGI video of Pentre Ifan in Pembrokeshire

It's 5,500 years old and one of the most distinctive features of the Welsh landscape, but now the Pentre Ifan monument has been given the benefit of 21st Century technology.

Thanks to CGI we can now see what the original burial chamber near Newport in Pembrokeshire would have looked like.

The unmistakable seven stone dolmen are all that remain of the ancient site.

Now a video reconstruction shows how they were once a doorway to the chamber.
