Hôtel de Marigny, Private mansion in 8th arrondissement, France

The Hôtel de Marigny is a 19th-century private mansion on Avenue de Marigny, set back from the street behind a large gate. Its classical main building has projecting pavilions and a return wing; the courtyard frontispiece carries four Corinthian columns framing a bay window and two niches beneath a triangular pediment. A vast basement housed the domestic services.

On 15 June 1869 Baron Gustave de Rothschild bought two townhouses from the Duchesse de Bauffremont for 2,700,000 francs, then merged them and added buildings from 1873 under architect Alfred-Philibert Aldrophe. The Rothschild family sold the property in 1971, and President Georges Pompidou had the state acquire it in 1972 as a guest house for foreign visitors, who had lodged at the Grand Trianon since 1959.

The mansion takes its name from the nearby Avenue de Marigny and serves as a setting where France receives foreign leaders with formal ceremony. Its grand reception halls reflect how the nation conducts diplomatic hospitality at the highest level.

The property sits directly opposite the Élysée Palace and is easily reached by public transport in this central district. Since it functions as a state residence, visitors can view the exterior but interior access is restricted to official guests.

In 1978, during a state visit to President Valéry Giscard d'Estaing, Romanian President Nicolae Ceaușescu and his wife took furniture and interior ornaments from the mansion, including gold taps torn off; the haul was estimated at several million francs. In December 2007, Muammar Gaddafi pitched his tent in the mansion's grounds during a diplomatic visit, causing controversy.
