The Palais de la Concorde is a large, cylindrical, fifteen-story building in Paris, United 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 Elysees, which it straddles, supported by four duranium beams at each corner that lead to the basement levels.
The first floor of the Palais features the chambers of the Federation Council, wherein the legislature meets for both full and sub-council sessions. The council chambers are rectangular; towards the south wall is the podium, typically used by the Federation President, or by another councillor, when presiding over a Council session. The podium is emblazened with the Great Seal of the United Federation of Planets, and the Federation flag hangs on a pole behind it. On the south wall is a viewscreen used for a variety of purposes, most commonly for tabulating votes during a session. The east and west walls feature matching rows of twenty seats each, with four rows on each side. (When the number of councillors exceeds the number of seats, two new rows of twenty seats each are installed on either side.) The center of the room is the area in which those acknowledged by the podium are allowed to address the Council or sub-council -- the speaker's floor. The northern side of the chambers features the gallery, an area of seating where spectators may observe full sessions of the Council; the galley is closed during classified sessions.
The second and third floors feature the offices of each councillor, while the fifteenth floor features the office of the Federation President, as well as the Ra-ghoratreii Room and Wescott Room and a waiting room for the president's secretary. (Under the Amitra and Jaresh-Inyo Administrations, the Ra-ghoratreii Room was used as the presidential office before Min Zife moved back into the primary office room on Fifteen.) The fourth through fourteenth floors feature the offices of the council's and president's staff, with the chief of staff for the president having an office on floor fourteen. The president's office is heavilly shielded, as are the Council chambers, to prevent breaches in security such as abductions. There are two transporter bays in the Palais -- one on the first floor and one on the fifteenth floor.
The Palais also features three basement levels, all heavilly sheilded. The basement levels, especially the Monet Room, are where the president, the presidential staff, and the members of the Security Council and other authorized councillors meet to discuss issues of Federation defense and security and to organize Starfleet operations.
- We saw the President's office on Fifteen in Star Trek VI: The Undiscovered Country and we saw the Ra-ghoratreii Room (serving as Jaresh-Inyo's office) in "Homefront" and "Paradise Lost" in season four of Star Trek: Deep Space Nine. We saw the Federation Council chambers in Star Trek IV: The Voyage Home, although it is possible that those were alternate chambers used in San Fransisco when the Palais is unusable for some reason, as the film strongly implied that the Council had been meeting in San Fransisco.
