One of the legends found in Għargħur is that of St. Patrick's Cave (Għar San Brinkat). It was believed, in the old times, that demons had infested this cave. Thus, people were afraid to pass by it. Once, a painting on wood that featured a crucified Christ and St. Patrick came ashore in Baħar iċ-Ċagħaq. Promptly, the people of Baħar iċ-Ċagħaq took the painting to this cave and the demons left. A spring found in this cave was said to be miraculous, however the faithful stopped drinking from it after lepers started bathing in it in order to heal. The painting can still be seen in the cave, a mass is said here once a year, when a small feast is held.
