In Northern Spain, not too far from the French border and just outside the village of Zugarramrdi, Navarre, there is a cavern that has been used for pagan rituals for centuries and rumored to be a meeting place for witches and witchcraft. The rumors led to the Spanish Inquisition to investigate the area in the 17th century and one of the largest witch trials in the world unfold with more than 7000 cases being looked into, implicating more than 5000 named people of all ages, known as the Basque Witch Trial.
The caves themselves are relatively flat with opening in both ends, with a small stream running through, and are still being used to celebrate summer solstice in a mid-summer festival.
On the way to the caves there is a witch museum, I won’t recommend to spend any time there as it was very disappointing, picturing more the daily life in the 17th century than a museum of witches and witchcraft.
Thanks for visiting!
