Where is it written about the Red and White dragons?

Greetings :) Yesterday there was a very chilled atmosphere in Glastonbury as people followed the red and white dragon procession up the high street and onto the fair field where a ritual marking the beginning of Summer was acted out. Gwyn ap Nudd handed over to Gwythyr ap Greidawl. All well and good but I fear that most people there have no idea where the red and white dragons spring from. Certainly not Glastonbury. They come from the legends of Merlin ( or Myrddyn as this was his real name) and specifically the building of Vortigern's tower. Myrddyn commented on why Vortigern's tower could not be built due to there being dragons underneath. He also prophesised about the portents of these two dragons. Here 's a pic of Dinas Emrys in Snowdonia. It s a great walk and where the aforementioned encounter took place ;) The view from on top Blessings B.C.

Hello all....if anyone is reading this :) Just over two weeks since I got back from a spiritual trip to Scotland via the lake district and Northumberland on the way back. Had epic weather and it has been too long since I visited. Great to take in the highland scenery and air. My travels took me via Castlerigg stone circle in the lake district and onto Roslyn chapel (extraoridnary). Then up to perthshire and the trossachs where I once again visited Kirk's faerie hill. Have to say the atmosphere was different...as if they ve left the place which was a bit disconcerting. Great drives around then I stopped near the Eildon Hills outside Melrose where Thomas the Rhymer met the Fareie Queen. All very inspiring and refreshing. Even walked a bit of Hadrians wall. The weather made it extra special :) Castlerigg stone circle Roslyn chapel Kirk's pine in Aberfoyle. Faerie hill in the Trossachs, Scotland. Is this where Thoas the Rhymer met the Faerie Queen who gave him 'The tongue that cannot lie' ? maybe ;)
