Organist Diane Bish and the television crew travel to the Fortress Cathedral in Sion, Switzerland to talk about and play the oldest playable organ in the world. A clip from "New York Times", Paul Hoffman: "One of the more unusual attractions of the Swiss canton of Valais is a 600-year-old organ, believed to be the oldest functioning organ in the world. It is housed in an 800-year-old fortress-church on a hill in Sion, the capital of the Canton. "The organ, built in 1390 and most recently restored in 1954, is mounted on a wooden pulpit jutting out like a ship's bow from the rear wall of the Romanesque-Gothic church, once the Cathedral of Sion and one of Switzerland's most haunting edifices."
