Wrapped in legend and mystery, the church of the "Fountain” also named “Of the Three Saints", is one of the most important places of worship and relevance of the city. It is in fact, built on the site where the Saints Alfio, Filadelfo and Cirino, today Protectors of Lentini, were martyred on May 10th, 253 AD. It was also dedicated to Saint Mercury Martyr, a Roman soldier who converted to Christianity after witnessing one of the miracles performed by the three young brothers.
