Château d'Aiguèze, Medieval castle in Aiguèze, France.

Château d'Aiguèze is a fortress built on a cliff above the Ardèche river, made up of powerful fortifications and natural troglodyte walkways. It has three towers: an 11th-century Saracen tower linked to a 13th-century round tower, and a 12th-century keep. A medieval-Renaissance seigneurial residence stands within the complex, and a long building with a tiled roof and two arched windows extends below the towers.

A fortification was established in the early 8th century to protect the region and assert control over the area following military conflict. In the late 14th century, the castle became the focal point of a local peasant rebellion and sustained significant damage during the resulting conflict.

The village of Aiguèze, grouped around the castle, is listed among the Plus Beaux Villages de France. The castle has belonged to the Romanet family since 1789; from 1901 Monseigneur Frédéric Fuzet, Archbishop of Rouen, began restorations of the castle, the 11th-century church of Saint-Roch and the village.

The castle is private property and closed to interior visits; the village streets and the cliffside paths give views of the round tower, the ruined square keep and the long tiled-roof building. The site faces Saint-Martin-d'Ardèche across the river, about 50 km northwest of Avignon.

The castle has belonged to the Romanet family since 1789, and Monseigneur Frédéric Fuzet, archbishop of Rouen, began major restorations of this family castle from 1901, along with the 11th-century church of Saint-Roch and the medieval village. The square keep's broken top, visible beside the round tower, shows the ruin left after the Tuchins' revolt and the destruction of 1389.
