The castle of Bovino was built by the Norman Count Drogone and later expanded by Frederick II, and in the 1600s it was transformed into a noble residence by the dukes of Guevara. Currently inhabited by the descendants of the Guevara family, in the past it was one of the most beautiful patrician residences in the South of Italy.
The Norman tower exists and is supported by a massive barbacane, in pyramidal shape. The construction is still retains good, between rocks and walls that partly retain vestiges of roman and hanging gardens. The castle stands on a rocky spur and overlooks the whole valley, famous for the raids of the bandits who, until the advent of united Italy, took to assaulting and plundering caravans and coaches that, from the Campania Region, to reach the Adriatic coast, were forced to pass through this narrow and dangerous throat between the mountains. The rooms of the Palazzo Ducale offer the visitor the possibility to appreciate the rich decor and visit the small but charming private chapel with majolica floor, where there is preserved a fragment of Sacred Plug, nestled in a cross of admirable workmanship, together with many relics of saints including a particle of purpura of Jesus Christ.
The first written record of church in Danmark locality date back to the year 1291. Close to the church are several stones with a Christian text and cross inscribed. The oldest parts of the present red-brick church are from the 1300s. In the late 1400s the church was enlarged to the appearance it has today. The church has been modified both internally and externally several times, among other things after the fires in 1699 and 1889. There are lot of well-preserved mural paintings in the walls.
