This basilica was built around the 10th century in honor of Saint Anthony, patron saint of navigators, and in c.1300 it became the home of the "Confraternita dei Battenti", an heretical confraternity originating from Naples. It was splendidly restored in the C17th by the Theatine Fathers. The crypt holds the tomb of Saint Anthony, where thousands of votive offerings have been made by sailors.
San Antonino is the patron saint of Sorrento, and an oratory dedicated to him was already in place by the 9th century. The present Basilica, however, dates from around the 11th century although much rebuilt over the centuries.
The columns inside are most probably Roman in origin, taken from some of the many seaside villas along this coast.
The crypt of the basilica contains the saint's tomb and an entirely fascinating collection of votive objects. Reminding me very much of the ancient Roman practice of casting an offering to the gods in the shape of whatever body part ails you, there are silver legs, eyes, noses, lungs, torsos....all sorts of body bits.....as well as effigies of people and babies. There are also several paintings of shipwrecks, presumably donated by those who were saved . Well worth half-an-hour or so of pondering.
The Basilica was erected in the XI century in the place where an antique oratory dedicated to Saint Antonino stood, there where rested the mortal remains of the Saint that here found refuge during the Longobard invasion.
The Church is rich with elements of spoil, like the column shafts coming, most probably, from the numerous Roman country homes present in the area.
