Temple de la Gloire, Neoclassical monument in Orsay, France.

Temple de la Gloire is a sandstone folly built in 1801 in the form of an antique temple, with a raised main floor above a ground level. Its eastern facade carries a triangular pediment and an upper balcony with a wrought-iron railing before a tall arched window; two short symmetrical wings give the plan a U shape. The western facade, facing the former canal axis, has a portico of four Ionic columns and two side staircases without balustrades.

Built in 1801 for Jeanne Perrin, widow of Gury Hulot and mother-in-law of General Jean Victor Marie Moreau, the folly was named by her for his victory at Hohenlinden on 3 December 1800. The plans are attributed, without certainty, to architect Pierre-Alexandre Vignon. On 23 May 1801 Moreau arrived by decorated gondola along the 1,200-metre canal to meet his wife and mother-in-law before the temple. The building was classified as a monument historique on 27 September 1979.

Jeanne Perrin named the building for her son-in-law Jean Victor Marie Moreau's victory at Hohenlinden on 3 December 1800. In the 1950s Sir Oswald Mosley and Diana Mitford lived here and gave the former temple a country-house interior, installing the state bed of the actor Talma, on which Napoleon is said to have taken lessons in oratory.

The building is a private, classified monument (since 27 September 1979) and is not open to visitors; it is seen from the gravel forecourt and the public lane along the Yvette. The former 1,200-metre canal of the Château d'Orsay, dug around 1764 to plans by Chevotet, is now partly filled in, so the western axis toward the temple is broken. Approach from the east side of Orsay, on the right bank of the Yvette.

On 23 May 1801 Jeanne Perrin staged her son-in-law General Moreau's return here: he came up the 1,200-metre canal of the château d'Orsay in a decorated gondola and landed before the temple's portico. The canal, dug in 1764 to plans by Chevotet, is now partly filled in.
