In 1886, Rudolf bought Mayerling, a hunting lodge. In late 1888, the 30-year-old Crown Prince met the 17-year-old Marie "Freiin" von Vetsera, known by the more fashionable Anglophile name Mary, and began an affair with her. On 30 January 1889, he and the young "Freiin" (Baroness) were discovered dead in the lodge as a result of an apparent joint suicide. As suicide would prevent him from being given a church burial, Rudolf was officially declared to have been in a state of "mental unbalance", and he was buried in the Imperial Crypt ("Kapuzinergruft") of the Capuchin Church in Vienna. Vetsera's body was smuggled out of Mayerling in the middle of the night and secretly buried in the village cemetery at Heiligenkreuz.
