Built on the site of an early Danish chapel (1095), this 17th-century edifice has fine interior woodwork and an organ (dated 1724) on which Handel is said to have played his Messiah. The humble, whitewashed interior is almost puritan in its simplicity, but it’s in the underground vaults where the church’s real claim to fame lies—and, be warned, it’s about as macabre as it gets. Something about the atmospheric conditions down here drastically slows decomposition. The mummified remains of several people have lain for centuries in an extraordinary state of preservation. A few still have their hair and fingernails; on others you can see desiccated internal organs under the skin. The tallest mummy is known as “the Crusader”; his legs were broken in order to fit him into the coffin. Others in residence include “the Nun” and “the Thief”; their true identities were lost when the church records were destroyed during the Civil War in 1922. It’s creepy as all get-out, but fascinating. It is said that Bram Stoker was inspired to write Dracula in part by having visited as a child. And we can believe it! Note: The church is wheelchair-accessible, but the vaults are not.
