James Hepburn—the fourth Earl of Bothwell and husband of Mary, Queen of Scots—died in a Danish prison and was entombed in a nearby church. Now his descendants want to bring what's left of the earl back to Scotland.
Bothwell's mummified body is currently in the vault of Farevejle church on the Danish east coast, where it has been preserved in remarkably good condition in an atmosphere rich in sea salt. Until 1975, when the Danish royal family intervened after pleas from Bothwell supporters, it was on open display as a grisly tourist attraction. [Link]
