Bardsey Island

Bardsey island is also known as a spiritual island and a doorway to an other spiritual world for the Celts and the Vikings1. Later, when the Christians came, it turned in a spiritual place for them (like many other ancient spiritual places).

This island is better known as the resting place of Merlin than Glastonbury. Some people say that Bardsey island was also called the fort of glass and that's a direct link to Merlin's resting place.

Location wise is Bardsey island a little bit more dislocated than Glastonbury but we still think it's a possibility.
