A locality intimately and indissolubly linked to the life and works of Saint Pio of Pietrelcina, it is a pilgrimage destination for the many faithful who come to visit the modern sanctuary, in which the Saint's relics are preserved, the result of an architectural project by the renowned architect Renzo Piano. The name of the town recalls the presence of a small church dedicated to St John the Baptist, known as 'della Rotonda' for its particular circular shape. The spirituality that pervades the daily life of the place goes well with the natural heritage of the Gargano Park that surrounds the town. The Grava di Campolato, the largest cavity in the Gargano and the deepest in Apulia, is a favourite destination for speleologists. Entering the mediaeval core, one can still see the ancient towers of the city walls, now converted into houses, and numerous churches.
