Site 117-91A is a SCP site located in Lexington Kentucky. The building housing the site is the historic Loudon House. The House itself is where most of the staff live and sleep, it is what’s underneath it that makes it special. The Loudon House was built on a large mine network where the original owner hoped to strike gold. Mr Loudon was a self made millionaire from his gold mines scattered throughout the country, at the age of 39 he suffered a severe psychotic break after the death of his wife. He ordered the mines dug in an area that his geologists on staff advised as having no signs of any valuable minerals. For several years Mr. Loudon had crews constantly digging and extending the mine network. Approximately 10 years of unsuccessful mining later he was convinced that his miners and geologist were holding out on him. He ordered that the mines be abandoned, and the house built on top of them. Designing the house himself he made a special concealed entrance to the mine as well as several secret passages in the home itself. Mr Loudon’s body was found 3 years after the finish of construction in his bed, still covered in dirt from the mine. Several years later it was purchased by an anonymous patron. The caves are now used for the storage and study of Safe and Euclid class SPC’s.
