You won't be surprised to hear that I am interested in the ancient symbolism of trees which is linked to ogham (my particular favourite is the hedgerow elderberry).
I just happened to spend an enjoyable day on the Pembrokeshire island of Caldey last week. Now the home to a Benadictine monastery it seems steeped in 'celtic' christianity but obviously predates all that. The little church of St Davids is built on a Celtic burial ground whilst the church of St Illtyd is the oldest place of catholic worship in the country and stands near to the island's natural water source. An ogham stone was found buried there - it is also has Latin inscribed on it. The story goes that 'Ned the Elder' who died around 1880 stated that other inscribed stones existed on the island but none have been found.
