Boville is also home to many Renaissance palaces and churches. Among them is the church of San Pietro Ispano, erected in the 12th century over the grotto in which for many years the Patron Saint lived. The church still conserves an early-Christian sarcophagus, two reliquaries, belonging to S. Pietro Ispano and S. Lucy, a chapel once belonging to the noble family of the Simoncelli, a Sansovino basrelief and a mosaic attributed to Giotto.
