It was a festival in Font-rubí and the neighbourhood danced in the threshing floor of Can Fàbregues (Fàbregas, nowadays), in the middle of the village. Three young girls were daughters of Can Fàbregues, who were dancing and enjoying the celebration until, interrupting the celebration, the priest appeared carrying the viaticum, ringing a bell and followed by three altar boys to announce the seriousness of a neighbour.

The musicians stopped playing and everybody kneeled before the holy man. Everyone except one of the three young women from the Fabregas estate, who kept on dancing. Right then she heard a deep, heavenly voice that told her: “You will be eternally condemned to live as a snake among the rubble of the castle. You will only be able to go out at midnight, on the Saint John’s day, to wash clothes at the Llinars fountain”. She turned into a snake and disappeared.

People later commented that they had seen her, “La Encantada”, in the night of Saint John, laying out white clothes or heading to the fountain to wash them, lit up with a red light. They also say that the spell will not be undone as long as there are descendants of Can Fàbregues.

In the other version, during the fiestas of San Juan in Font-rubi, the three young ladies were dancing and enjoying themselves until one of them fell down a well. As she was beyond saving, she cursed the family and on the night of San Juan she comes out in the form of a snake to seek out for a descendant of the Fàbregues family to trade places with her and thus end her captivity.

Just in case… we never go to Font-rubí for San Juan, lest the legend be true.
