The Pennsylvania Convention Center comprises four main halls or rooms, smaller meeting rooms and auditoriums, and the Grand Hall, which occupies much of the trainshed of the former
Reading Railroad terminal. The rest of the train shed is occupied by meeting rooms and a hallway on the main floor, and the Grand Ballroom on the upper floor. The
headhouse entrance to the Convention Center is located at 12th and
Market streets in
Center City. The A, B, and C exhibit halls extend across 12th Street, one story up (the 200 level) from the street level (100 level), between 11th and 13th streets and
Arch and
Race streets. At the south side of the A exhibit hall, a walkway extend over Arch Street, south into the grand hall. The opposite end of the grand hall provides a gated entrance into the headhouse lobby for the
Marriott Hotel that occupies the old office spaces of Reading Railroad. Access to an adjoining Marriott Hotel is gained from this lobby by means of another second-story walkway over 12th Street. The hotel, designed by BLT Architects with completion in 1995, is connected to the Market East Station via a skybridge to the historic
Reading Terminal. The 1,200-room hotel also offers restaurants, a health/fitness center, and various-sized ballrooms and pre-function areas for meetings, convention activities, and other public and private events. In 1999, designs by BLT Architects to expand the Marriott Hotel at the Pennsylvania Convention Center were completed. The upper seven floors of the historic Reading Terminal Headhouse, designed by the Wilson Brothers in 1894, provided space to expand the Marriott's conference capabilities with a 210 unit suites-type hotel featuring terraced restaurants and other public spaces. The grand ballroom occupies the Reading Railroad Company’s original waiting room. ==Reading Terminal==
