Hôtel de Béarn

Hôtel de Béarn is a 19th-century private mansion in the 7th arrondissement of Paris, standing at the corner of rue Saint-Dominique and avenue Bosquet, within walking distance of the Champ de Mars and the Eiffel Tower. Also known as Hôtel de Béhague, it has served for decades as the Embassy of Romania and remains one of the quieter but historically rich addresses on the Left Bank.

Where does this mansion come from?

Construction began in 1866, commissioned by Count Octave de Béhague and designed by architect Hippolyte Destailleur, who was already well known for building residences for Paris's aristocracy. The original design followed the taste of the Second Empire, an era when wealthy families favored grand townhouses in the newly developed neighborhood around the Champ de Mars.

Why does the building carry two names?

The Béhague name traces back to the first owner, while Béarn comes from the title of his heiress, Martine de Béhague, Countess of Béarn. After inheriting the property in the late 19th century, she commissioned architect Walter Destailleur, a relative of the original builder, to carry out an extensive reconstruction. The work, spanning 1895 to 1904, involved demolishing much of the earlier structure while retaining parts of it. The project was first envisioned in a neo-Byzantine style, though the finished 1904 building blended those forms with classical architectural elements.

What makes the interior distinctive?

The Countess of Béarn was a noted collector of art, historical artifacts, and literary works, and she turned the mansion into a showcase for her collection as well as a gathering place for cultural figures of her era. The most singular feature inside is a private theatre known as the Salle Byzantine, designed by the Spanish artist and stage designer Mariano Fortuny y Madrazo. It was fitted with an organ built by Charles Mutin, successor to the famed Cavaillé-Coll workshop, and formally inaugurated on 29 March 1906.

How did the mansion become an embassy?

In 1939 the property was purchased by King Carol II of Romania, marking the start of its diplomatic role. Since then, the building has continuously housed the Embassy of Romania in France and remains state property of Romania. Given its architectural and historical significance, it was listed as a monument historique on 25 August 2003, a protection that covers the addresses along rue Saint-Dominique, avenue Bosquet, and rue de l'Exposition.

What should visitors know before stopping by?

Hôtel de Béarn is neither a museum nor a publicly accessible sight — as a working embassy, it does not offer regular interior tours. Its interest for visitors lies mainly in its exterior architecture and its place within the elegant Palais-Bourbon quarter, a district that mixes diplomatic residences, government ministries, and 19th-century apartment buildings.
