The Pulicchio of Gravina is one of the largest karstic cavities in Puglia. It is located in the Alta Murgia National Park, 10 km from the centre of Gravina in Puglia.

Legend has it that only seven churches have survived over the centuries: those of Santa Maria di Monteverde, Maria Santissima Assunta di Ferrazzano, San Leonardo di Campobasso, Santa Maria di Cercemaggiore, Santa Maria della Strada di Matrice and the cathedral of Volturara Appula, while the name of the seventh remains obscure. The origins of the church, in honour of the Madonna, are linked to the period when the feud of Matrice was ruled by Roberto Valerio and it seems that he himself donated the land on which the monument stands. The construction of the church can be dated around 1100, and it was consecrated in 1148 by Archbishop Pietro and bishops Giovanni di Volturara, Raimondo di Cividale and Roberto di Bojano.

The date of construction of the fortress is 1382., which had to defend the city from the sea. The fortress represents the beginning of a medieval town founded by the Bosnian king Tvrtko.
