Sector 1
From Tardis Wiki, the free Doctor Who reference
In the Capitol, Sector 1's main tower housed the Panopticon, a vast hexagonal chamber in which great events of state were held. Elsewhere in the tower was the Capitol Museum, where the symbols of presidential office were on display, along with examples of every kind of robe of state, from the President and the Gold Usher to the Chapter Cardinals.
