Château de Kervoazec, 19th-century castle in Saint-Goazec, France.

Château de Kervoazec is a 19th-century building in Saint-Goazec, Finistère, set in a park that now covers 8 hectares. Its pale grey stone facade has rows of white-framed windows, a steep dark slate roof with dormer windows and brick chimneys, and a white-framed glass conservatory along the front. The estate retains gardens and a spring-fed pond.

The castle was built in 1850 by Louis Monjaret de Kerjégu on the site of the former village of Tregoazec. Its founder established it as a farm school and horse breeding center.

From 1916 to 1928, the estate housed a lace-making workshop led by Geneviève de Rouvroy de Saint-Simon. This craft activity brought together local artisans and shaped cultural life in the region during that period.

The estate now covers 8 hectares, the rest having been sold off during the 1950s. The spring-fed pond on the grounds is still exploited commercially; the water is bottled under the brand name "Isabelle". Ker Maunoir, the house built for Eudes de Rouvroy de Saint-Simon's daughter, stands at the far end of the park.

During May 1944, the estate served as a gathering center for children from Brest living under German occupation. This lesser-known chapter in its history reveals how the place was used during World War II.
