Tallinn's most famous work of art, a wall-sized fragment of Bernt Notke's spooky, 15th-century masterpiece Dance Macabre, has its home in this 13th-century Gothic church-turned art museum. Destroyed during World War II and rebuilt during Soviet times, the church now houses a fascinating collection of medieval religious art, with altars from the 15th and 16th centuries, a collection of Baroque and Renaissance chandeliers, and a 'silver chamber.' The church is also known for its acoustics - organ concerts are held here every Saturday and Sunday at 16:00.
