Zugarramurdi is a town and municipality located in the province and autonomous community of Navarre in northern Spain. It passed into history as the setting of alleged occult activity featured in the infamous Basque witch trials held in Logroño in the seventeenth century. The town is home to the Basque witch museum and the Witch Caves. Every year, spectacular fires are lit in the caves near Zugarramurdi for the celebration of the ‘day of the witch’ on the summer solstice.
