Not far from Sant’Angelo and the Aphrodite Apollon spa gardens, on one of the hottest thermal slopes of the island, in a small patch of beach of the Maronti, for centuries the breath of Tifeo has escaped from the depths of the earth. A very interesting phenomenon due to the volcanic activity of the island of Ischia: "le Fumarole".The Olmitello spring is located in a valley behind the Maronti beach, it was believed to be capable of rounding off the calculations (stones) and making them expel (as the origin of its name indicates from the Greek round stone I do).The source is located in the southern part of the island, about a third of a mile from the sea, in an overhang between the rocks that opens onto the Maronti beach; it was made accessible by Count Giorgio Corafà, who stayed in Testaccio until his death in 1775.
