Château de Marsillargues, Castle in Marsillargues, Occitanie, France.

The Château de Marsillargues is a pale stone complex in Marsillargues, Hérault. Its north wing, rebuilt around 1560 for Jean de Louet de Calvisson, has a raised storey between a battered base and a blind attic under a flat roof, with windows crowned by alternately curved and triangular pediments. A long wing carries a carved frieze and a row of vertical niches; a tall square tower with a small round turret stands beside it.

Guillaume de Nogaret founded the castle in 1305 as a reward from King Philip IV of France for his service. The fortress later underwent major transformations that shaped the structure we see today.

The orangery has been converted into a municipal library that serves the local community with books and cultural events. This transformation shows how historic spaces continue to have meaning for people today.

A major restoration project began in 2022 to renovate the north wing and develop museum spaces within the building. Visitors should check ahead about ongoing work and expect varying access depending on construction phases.

The night fire of 19–20 May 1936 destroyed the Louis XVI gallery, the library and the grand staircase in the north wing; only the Renaissance facade survived. From 1935 the caretakers Marie "Mariquette" and Élie Rouvière lived on site, and after the town bought the castle in 1948 they opened its gates daily while village children played in the overgrown courtyards.
