There is a castle inside the extinct volcano of Roccamonfina, on a natural saddle in the territory of the municipality of Conca della Campania. Its origin coincided with the birth of the fief of Conca in the12th century. The castrum, with a major tower in the south-eastern corner, was then reinforced with a belt of straight walls and watch towers.
Dates back to that period a new wall built along the perimeter of the fortified complex. But in the 14th century, when the fortress passed as Conca under the control of the Marzano, dukes of Sessa, three wings were built, to the east, west and north, lined in a horseshoe and developed on three floors. With the arrive of the viceroyalty, in 1467 the principality of Conca was created for the benefit of the Di Capua family, who did not fail to improve the structure of the castle. The main tower was demolished and replaced with a hanging garden and the fortress was gradually transformed into a Renaissance palace with a fine hall and a cycle of frescoes still visible today. And as such, the subsequent owners of the fief, the Invitti and the Galdieri, used it. On the main floor there is a statue of particular value dating back to the 17th century made in cedar from Lebanon depicting the Madonna della Libera.
