Château de Châteaugay, Medieval fortress in Châteaugay, France.

Château de Châteaugay stands above the village of Châteaugay and the Clermont hills. Its square crenellated keep rises beside a lower stone range with rectangular windows and a steep red roof, and a white building with dark-shuttered windows adjoins it. Two round towers, the Fort and the Perrière, were added around 1430.

The first lords of Vigosche are recorded around 1270, when the seat was a fortified house above Pompignat. In 1381 Pierre II de Giac, chancellor of Charles VII, built a central building with watch turrets on that site and named it Château-Gay, after the domain gained high-justice rights in 1379 and a market in 1384. Two round towers, the Fort and the Perrière, were added around 1430.

The name Château-Gay was given by Pierre II de Giac in 1381, and the domain gained high-justice rights in 1379 and a market in 1384. Guillaume Revel's 15th-century Armorial depicts the castle with its square crenellated keep, round towers and enclosure. In May 1789 Lafayette and the marquis de La Queuille met here to prepare the reforms of the Estates General.

The castle stands above the village of Châteaugay and overlooks the Clermont hills; the visit is self-guided through the keep and the round towers Fort and Perrière. The site is visitable, but the sources give no opening days or seasons, so check locally before going. The grounds were altered in the early 19th century when the moats were filled in and the outer walls demolished.

In May 1789, the castle hosted meetings between the Marquis de Lafayette and the Marquis de La Queuille to prepare the reforms of the Estates General and the abolition of privileges by the delegates of the three orders gathered at Riom. The round towers Fort and Perrière, added around 1430, appear in Guillaume Revel's 15th-century Armorial with the square crenellated keep.
