It is generally agreed upon that the world's oldest playable pipe organ is located in the Basilica of Valère in Sion, Switzerland. Built around 1435, most of the case is original, but only 12 pipes are original, as the rest have been replaced during restorations. It is said that the organ in the church of St. is another strong contender for this title.
While the oldest playable organ is a fascinating discovery, the question of which organ is the oldest in terms of the human body is more complex. Scientists have discovered that the oldest cells in the body are not neurons or heart cells, as once believed. Instead, the age of an organ can vary, and researchers can now estimate the age of 11 major organs, including the heart, brain, kidneys, and liver. There is no single answer to the question of which organ is the oldest because the age of an organ can vary from person to person.
