Castel Madruzzo, Medieval castle in Madruzzo, Italy.

Castel Madruzzo is a medieval castle above the hamlet of the same name in the municipality of Madruzzo, province of Trento. A circuit of walls encloses a central courtyard onto which the various buildings face. The south side holds habitable palaces mostly of 16th-century origin, while the north side, including the keep, still lies in ruins. A 12-hectare park surrounds the castle.

The first documents on the castle date from 1161, when Prince Bishop of Trento Adalpreto II granted it as a fief to Gumpone and his nephew Boninsegna, founders of the first Madruzzo family. After the male line died out in 1380, the castle passed to the Roccabruna in 1389, then to Sigismondo Stetten in 1441 and to Aliprando di Denno-Nanno in 1447. His nephew Giangaudenzio took the name Madruzzo, and his son Cristoforo began the Council of Trent.

The Madruzzo family's connection to the Bishops of Trento shaped the region's identity, and their residence displays the wealth that such religious authority brought. The architecture here reflects both spiritual and earthly power.

The fortress sits on a hill with valley views and remains visible from outside, but entry is not currently permitted. The location is reachable from Madruzzo village and offers photographic opportunities from a distance.

The castle's name comes from Giangaudenzio of the Denno-Nanno family, who inherited it in 1447 and began calling himself Madruzzo, adopting a coat of arms modelled on that of the earlier, extinct family. The second Madruzzo line he founded produced Cristoforo Madruzzo, who opened the Council of Trent.
