Castle of Corniglio, Medieval castle in Corniglio, Italy.

The Castle of Corniglio is a medieval defensive structure on a rocky spur between the Val Parma and the Val Bratica in the province of Parma. It is now the seat of the municipal offices; little of the original building survives, but the west wing, the massive wall spurs and two corner bastions date from the Rossi period, and a neoclassical shrine to Saints Lucio and Amanzio stands in the courtyard where a Benedictine oratory once was.

The castle is first documented on 6 February 1240, when Guglielmo de Egidiis ruled against Bishop Martino of Parma in a dispute with the Platoni of Val Taro; a moat surrounded the structure by then. In 1296–1297 Manuello da Vallisnera seized it and handed it to Marquis Azzo VIII d'Este before surrendering to Parma's troops. Bishop Ugolino de' Rossi took refuge there in 1329 and ceded the fief to his grandson Giacomo in 1355. The Rossi lost it in 1483 after Guido's defeat; Filippo Maria de' Rossi retook it in 1521.

The castle has housed Corniglio's municipal offices since 1860, after Duchess Maria Luigia gave it to the town in 1820. In the courtyard, a Neoclassical shrine dedicated to Saints Lucio and Amanzio stands where a Benedictine oratory once was, and the clock turret belongs to later renovations.

The castle stands on a rocky spur between the Parma and Bratica valleys and now houses Corniglio's municipal offices, so visits are limited to the exterior and courtyard. The west wing, the perimeter wall spurs and two corner bastions survive from the Rossi period; the clock turret belongs to later rebuilding.

The castle is still Corniglio's town hall, as it has been since 1860. In the courtyard, a neoclassical shrine to Saints Lucio and Amanzio stands where a Benedictine oratory once was, and the clock turret belongs to later rebuilding rather than the medieval phase.
