The feast of San Juan (St. John the Baptist) is June 24th.
Many people light bonfires on St John’s Eve. In the days before municipal rubbish collection, it was a practical way of having a clear out. But in Puntallana, there is a long-held folk belief that the bonfires keep away witches. Jumping over the fire is supposed to protect you from disease and the Evil Eye. It’s also a great night for fortune telling, using earth, air, fire and water.
I’m sure hte people celebrating would insist that this is a Catholic festival, and nothing at all to do with the Wiccan Midsummer celebrations, which also feature bonfires.
