Halberstadt
Germany
Since 2001, the church of Sankt Burchardi in Halberstadt has been the site of a performance of John Cage's ORGAN²/ASLSP — a piece designed to last 639 years, making it the longest-running musical performance in the world. This town in Saxony-Anhalt, known as the Gateway to the Harz Mountains, also holds a Gothic cathedral and the Martinikirche, around 450 timber-framed houses in its centre, and a history as a bishopric from the 9th century until 1648. More than 80 percent of the old town was destroyed in a 1945 bombing raid; much has since been restored.
