3. The world's oldest playable pipe organ
With 12 of its pipes dating from around 1435, the oldest playable pipe organ in the world is located at the fortified Basilica of Valère in Sion, Switzerland. The organ's pipes were arranged to form a rough outline of a church; the larger ones forming two towers, and the smaller ones creating a triangular church roof. Very sweet.
