What is the Entresol floor and why are the rooms on this floor numbered in the 500s?
An Entresol or mezzanine consists of an intermediate floor directly above the ground floor. As shown by the square footage, it is considerably smaller than the other floors of the Capitol. The Entresol in the Capitol serves to allow the first floor corridors to be higher than they would be otherwise. The E-floor has always been numbered as 500 series of rooms as designed by architect Joseph Huston.
