Château des Brétignolles, Gothic castle in Anché, France.

Château des Brétignolles is a castle estate near Chinon featuring a medieval tower, Gothic chapel, and symmetrical auxiliary buildings arranged around the main grounds. The core structures were built between the 15th and 16th centuries, while the surrounding outbuildings were added in the 18th century.

The land was documented in the 9th century during the reign of Charles II the Bald and belonged to Marmoutier Abbey before the Bernard family transformed it into a castle between 1450 and 1480. This shift marked the transition from religious to private noble ownership.

The name Brétignolles comes from the 9th-century Latin Britanniolae, meaning "small colony of Bretons", recorded in a diploma of Charles the Bald. The estate passed by marriage into the Turgot family in 1718 through Madeleine Françoise Martineau, daughter of Guillaume Martineau, who owned it from 1706.

The estate lies on the left bank of the Vienne, north of the river, between Chinon and L'Île-Bouchard in the commune of Anché, Indre-et-Loire. It is reached by road from either town. The castle, chapel and 1732 outbuildings stand within the grounds; the entrance arch opens at the base of the central tower.

The name Britanniolae, recorded in a 9th-century diploma of Charles the Bald, means "small colony of Bretons". The seigneurial chapel is dated 1507, and the outbuildings were built in 1732. The estate was bought by a Norman family in 2016.
