Castle of Roccalanzona, Castle ruin in Roccalanzona, Medesano, Italy

Castle of Roccalanzona is a medieval fortification built on elevated ground with thick stone walls, reinforced towers, and strategic defensive positions. The structure commands the surrounding valleys and hills with its solid presence.

Built probably around the 10th century, the castle is first documented in 1028, when it was listed among the possessions of Ildegarda, wife of the Lombard noble Odone, and sold to the rector of San Pietro di Paderna. In 1043 the lands passed to the monastery of San Savino di Piacenza. Long contested between the Pallavicino and the Vinciguerra, it went to the Rossi in 1418 through a bequest by Giacomo de' Rossi; Pier Maria I renamed it "Rocha Leone" after the family's rampant lion. In 1482 Guido de' Rossi defended it against Sforza Secondo Sforza, who withdrew after burning houses in the village.

The name Roccalanzona derives from the 1028 document's "Rocha Petraluizoni", while Pier Maria I de' Rossi renamed it "Rocha Leone" after the rampant lion of his family crest. A chapel stood by the castle until its demolition in 1739. The ruins appear in Benedetto Bembo's 1463 fresco in the Camera d'Oro of Torrechiara.

The ruins stand on an ophiolitic rock spur above the Ceno valley, near the hamlet of Roccalanzona in the municipality of Medesano. The site is reached on foot along trails; the terrain is steep and the remains are scattered over a wide area, so allow time to walk between the walls and the keep.

The castle appears in the background of Benedetto Bembo's 1463 fresco in the Camera d'Oro of Torrechiara, painted at its height. Look for the remains of the rectangular keep and the vaulted room with its cross-shaped loophole, the most intact part of the ruin.
