Château d'Opme, Castle in Romagnat, France

Château d'Opme is a castle of rough grey stone blocks in Romagnat, south of Clermont-Ferrand. Its facade has a tall round tower at the left edge and a lower rounded section at the right; rectangular windows with dark red frames sit in lighter stone surrounds, and the central door, reached by a short flight of stone steps, carries a small wooden balcony above it. The building is arranged around an interior courtyard.

The castle was built in the late 11th century to control the Roman road connecting Clermont to Puy-en-Velay. Its location made it a valuable possession for the Counts of Auvergne, who ruled the region.

The gardens display formal French design with two terraces and a circular basin, showing how noble families shaped their estates. A Renaissance fountain designed by Androuet du Cerceau adds to this carefully planned layout.

The castle and gardens can be visited from Easter to All Saints' Day. The site lies at the hamlet of Opme in the commune of Romagnat, about nine kilometres south of Clermont-Ferrand, and the château guarded the pass of the old Roman road to Puy-en-Velay. The gardens have held the Jardin remarquable label since 2004.

General de Lattre de Tassigny established a military training school here in 1940 to prepare soldiers for combat. A museum dedicated to him now occupies the space, keeping his story alive for visitors.
