The mausoleum was once the home of a host of undead which were destroyed by Corrie, Malleus, Relg and Artemis when taking possession of Stanzfeld mansion. One of the coffins was revealed to be an entrance to a tunnel which lead to the underground complex beneath the lake and gardens.

Since then, the coffins have been removed and a trapdoor installed over the tunnel. It is currently being used as a store room, although it has been considered as an accommodation overspill, although doubt has been expressed over whether anyone would want to stay in a converted mausoleum!
