Château de la Source, château in Orléans, France

Château de la Source is a manor house situated beside the Loiret River, near the water source called Le Bouillon that inspired its name. The building stands close to the Floral Park and currently serves as administrative offices for the University of Orléans.

The château was designed in 1633 by Charles Turmel and represents 17th-century architecture. Between 1710 and 1723, the English nobleman Henry St John, First Viscount Bolingbroke, rented the property and made it his residence during those years.

The name comes from the spring called Le Bouillon, 250 metres from the building, which feeds the Loiret; the château stands above the water mirror along the stream. Voltaire gave the first reading of La Henriade here, and the English exile Henry St John, Viscount Bolingbroke, rented the estate between 1710 and 1723.

The château houses the administrative services of the University of Orléans, so the interior is not open to visitors; the stone facades and the slope above the water mirror can be seen from outside. Tram line A stops at Université-Château, and departmental road 14 also passes nearby. The Loiret stream and the Bouillon spring lie about 250 metres away, next to the Floral Park.

The site held military importance after a major European conflict, when Marshal Louis Nicolas Davout used it to coordinate the withdrawal of troops. This demonstrates that the château served purposes beyond its original role as a private residence.
