The Palais de la Concorde (pronounced: pah-LAY de la con-CORD) is a large, cylindrical, fifteen-story building in Paris, France on Earth, that serves as the seat of government for the United Federation of Planets. The Palais is located on the site of the former Place de Concorde and is elevated above the Champs Elysées, which it straddles, supported by four duranium beams at each corner that lead to the basement levels.
- In the continuity of Last Unicorn Games, the office was known as Empyrean House. (The Dominion War Sourcebook: The Fires of Armageddon)
In 2372 (in the Pendragon timeline), the Palais was placed under lockdown by Admiral James Leyton after martial law was declared on Earth. Nonetheless, a Changeling infiltrated the building and assassinated Federation President Jaresh-Inyo. (Star Trek: Pendragon)
