Château de Gacé, Medieval castle in Gacé, France.

Château de Gacé is a quadrangular brick and stone building in the centre of Gacé, with a projecting central pavilion. Its north-west corner rests on the 14th-century Talbot Tower, crowned with machicolations and a pepper-pot roof of limestone and ochre sandstone laid in irregular chequers. Two brick round towers built in 1449 flank the west facade, and a segmental arch porch leads inside.

Gacé was fortified by the dukes of Normandy around the year 1000 to offset the ruined defences of Sées; its first known lord, Raoul de Gacé, died in 1051. The castle was rebuilt by Jean II and Jean III de La Ferté-Fresnel after damage in the Hundred Years' War, and passed to the d'Estouteville family around 1414. The English-held fortress was retaken in 1445, and the west tower, called tour Talbot after an English captain, dates from that occupation.

This fortress represents medieval power in Normandy and shows how the land was controlled in earlier times through its physical layout and stone structures. Visitors can see traces of how important families once ruled from this location.

The castle stands in the centre of Gacé, and its brick-and-stone façades and roofs have been listed as monuments historiques since 6 May 1968. It now houses the town's municipal services and a small museum devoted to Marie Duplessis, so access follows the opening of these offices rather than a separate ticket desk.

The two brick round towers flanking the west entrance were built in 1449, during the English occupation, and are preceded by a drawbridge. The north-west tower, crowned with machicolations and a pepper-pot roof, is built in irregular checkerwork of limestone and ochre sandstone known as "roussier".
