The main gallery in the 63,700-square-foot building is approximately 210-feet-long, 160-feet-wide, and 70-feet-high. The largest gallery features a 70-foot by 70-foot pivoting door, as well as a functioning industrial bridge crane-hovering close to the ceiling and suspended from tracks at either side of the space-with a lifting capacity of 35 tons. The main floor of the large gallery is breached by a 210-foot by 30-foot trench, which can either be covered with 21 five-ton trench covers to create a single level, or the trench covers can be selectively removed to reveal the galleries on the lower level. The lower level is accessed either by escalators or via a 30-foot-wide lime green processional staircase. A skylight in the ceiling-125-feet by 70-feet-features motorized trap covers, located on the roof, which can either filter out all natural light or be fully open to the sky. In a gesture to the Las Vegas aesthetic, the underside of the skylight is covered with a large-scale facsimile of the central scene from Michelangelo's Sistine Chapel ceiling. A media wall that is 60-feet-high and 120-feet-wide comprises the northern wall of the main gallery.
