The Boscastle Museum of Witchcraft has been located in the Cornish village of Boscastle since 1960 and houses the worldÕs largest collection of witchcraft related artefacts. The museum was founded by Cecil Williamson (1909-1999) who worked undercover for MI6, collecting data on occult interests of military personel in Nazi Germany through WW2 and used occult knowledge to lure Rudolph Hess to Scoltand. Williamson was a colleague of Wallis Budge (1857-1934), Egyptologist at the British Museum.

Since 2000 Boscastle has held the Richel collection. Richel had inherited much of his collection from his father in law, Eldermans, who had been a Magister of the Ars Amatoria, a group using sexual magic. Both were members of the Mysteria Mystica Maxima (.'M'..'M'..'M'.). The Museum also contains artefacts from Aleister Crowley's occult group, the Argentum Astrum (Silver Star). Richel and Eldermans are believed to have been members of another occult group based in The Hague and Leiden.
