Edinburgh!
The Beltane Fire Festival has been going on up Calton Hill since 1981 (I think- I was there in 82, and I don't think that was the first one). Back then it was started by the Ministry of Works AKA Test Dept. as a way of re-establishing the old rites and faiths. It was basically a small marquee with a huge Beltane Bonfire- folk did turns in the marquee etc and Beltane Bannock was cooked for all of us. All very quaint. Nowadays- it's huge- a victim of it's own success perhaps- I've not been for a few years, but there are thousands upon thousands of folk go. Last time I went was a bit chaotic and the procession went anti-sunwise which I thought was a bit odd. Afterwards many folks head up Arthurs Seat to watch the sun rise and wash their faces in the dew (and join the Christains who hold a Mayday ceremony up there!).

I do believe they'll be performing their Samhuinn festival tomorrow night....
I'd like to think that in the more rural and obscure locales of Scotland that mnay of the fire festivals, rites and traditions are upheld, but I fear it may be rose-tinted specs! Have you got F. Marian McNeill's "Silver Bough"?? It lists all Scottish festivals from national to local- was written in the late 50's, but still a fascinating read,
Hope that's of use,
Martin
