The Boleskine House, located on the southeastern shore of Loch Ness in Scotland was owned by Crowley from 1899 to 1913, during which he attempted to perform the Abramelin ritual, a complex magic ceremony aimed at contacting one's guardian angel (well, let's not go into the debate about the HLA here). I have visited the area and graveyard just in front of it several times, but never visited the house itself out of respect for the owners at the time. In recent history, the house has faced several misfortunes, including a fire in 2015 that severely damaged the property, and another fire in 2019, amidst efforts to restore and preserve the site. The website offers some basic information, ability to donate or buy non-Crowleyana merchandise.
