#16: The Skull of Saint John the Baptist
The Skull of Saint John the Baptist, fiercely claimed by several ancient religious sites across Europe and the Middle East, is most famously housed in Amiens Cathedral, France. Brought back by French crusaders in 1206 after the sack of Constantinople, this revered relic inspired the construction of the stunning Gothic cathedral that stands today, becoming a focal point of veneration for generations of pilgrims.
