Château Morange, Historical monument in Saint-Denis, Réunion Island.

Château Morange is a neoclassical mansion on Boulevard Doret in Saint-Denis, built around 1850. Its single-storey white main building has a flat roofline topped by a balustrade and a portico of four plain round columns above a low stone stair; behind them are two white panelled double doors and a dark doorway. The main building comprises several wings with a colonnaded portico forming a front veranda and an external service stair, built of lava stone, rubble, brick and render under a metal roof.

Prosper Morange commissioned the house, built around 1850 by contractor F. Chatel in the Camélias district, at the foot of the road to Saint-François. After the sugar economy collapsed from the 1860s, it became a prison for exiles, including Moroccan leader Abdelkrim al-Khattabi from 1926 to 1929. The building, its patio, park, outbuildings and fences were listed as historical monuments on 13 December 2010.

Since the sugar economy declined, the building has been put to public use; it now serves as the Maison des Jeunes et de la Culture of Saint-Denis, with a 110-seat performance hall. The name "château" is a local usage for a grand bourgeois mansion rather than a fortified castle.

The building stands on Boulevard Doret in the Camélias district, at the foot of the road heading toward Saint-François. It now operates as a Maison des Jeunes et de la Culture, so access depends on the centre's activities; the performance hall seats 110. The château, patio, park, outbuildings and fences have been listed as historical monuments since 13 December 2010.

After the sugar economy collapsed from the 1860s, the mansion was turned into a prison. The Moroccan leader Abdelkrim al-Khattabi was held there from 1926 to 1929, after his Rif War defeat, making this suburban villa a place of internment rather than a residence.
