Château du Grand-Blottereau

Château du Grand-Blottereau is a classical château in Nantes featuring balanced proportions and symmetrical facades characteristic of 18th-century French design. The property encompasses tropical greenhouses, ornamental gardens, and sports facilities now open to the public.

Built in 1747 under architect Jean-Baptiste Ceineray for Gabriel Michel, a director of the French East India Company, the château reflects the wealth of 18th-century merchant elites. It received official monument protection in 1992.

The château stands as a landmark where visitors can see how an 18th-century private residence has become part of the public landscape. The surrounding grounds reflect the blend of aristocratic heritage with contemporary communal use.

The main building remains closed to visitors, but the surrounding park and gardens are open to the public. Visit during daylight hours to fully enjoy the landscaped grounds and greenhouse displays.

The château served as an American military hospital in 1917, connecting this French property to World War One's broader history. Few visitors realize the building once sheltered soldiers from across the Atlantic during the conflict.
