The Portal and the Cosmos
Poulnabrone Dolmen portal tomb in the Burren, County Clare, Ireland. It dates back to the Neolithic period, probably between 4200 BC to 2900 BC.
I took this photograph at 4am on clear Spring night. There are no cities or villages close to the Dolmen so there was not much light pollution so you could see a huge amount of stars in the sky. I lit the tomb with a torch so it stood out against the night sky.
