Some years ago, my friend Mike took me on a tour of London, which included among other things some of the famous occultist Aleister Crowley's haunts. Always up for a little mystery, and coming from the significantly more occultly pregnant city of Salem, Massachusetts, I was excited to be led on a short tour of this sort in downtown London, by my good friend the Neo-Shaman.
The UK is the birthplace of modern Witchcraft and Neo-Paganism as we know it today, and London of course is going to be "the spot" for learning much of this history.
Atlantis Bookshop was one of the strange old man's frequented places, and it still stands, and is still active today. This is also true for Watkin's Books, which has been around for over a hundred years.
Locations such as 67-69 Chancery Lane where the strange old occultist once lived, and practiced his arts can be seen, and The Plough - a Pub and another hangout on Museum Street should be stopped at. These dark and peculiar places in London bring you back to the turn of the century over a hundred years ago, and can give you a significantly creepy sense - unless of course, like me, you are comfortable learning about our wild, weird and wonderfully diverse world.
This is on my list of 1,000 things to do before I die. I haven't died yet, and I've accomplished it - and it didn't kill me.
When you make this a part of you trip to London you will want to find hotels in London City Centre with parking.
