The Knights played their home games at the Omni Coliseum . It stood for 25 years as the Atlanta area's primary indoor spectator sporting arena. The Omni was easily recognized by its square outline and its unusual steel-egg-carton designed roof. The roof design served to allow a larger building without need of internal roof supports. The Omni was demolished soon after the 1996-97 NBA season to make way for a new multipurpose coliseum -- Philips Arena.
The Omni was an eyesore, to be sure, with its 1970s brown metal exterior and distinctive (but very ugly) egg-carton roof. It had no amenities to speak of -- no luxury boxes, no club seating, only one restaurant, no video or replay boards, a single, narrow concourse, limited parking, and inadequate restroom facilities. It had a number of quirks, such as "the Well" in the upper deck -- the walkway around the upper deck was between the first and second rows, separating the first row into its own level that overhung the lower deck. It was bug- and rat-infested and the office complexes in the building, designed for the teams that played there, were accessible only through an assortment of underground passages.
The Knights called the Omni home from their inception in 1992 to their final game in 1996. During that time, there were virtually no improvements made to the Omni's infrastructure, neighborhood, or amenities. Knights fans didn't care -- they were there for the hockey -- but the lords of the Atlanta Hawks were missing out on the lucrative luxury box, merchandising, and concessions income that would come from a lavish new arena. So, it was announced, after the 1996 Olympics, the Omni would be torn down and replaced with a new palace.
The main gondola scoreboard from the Omni now hangs in the Philips Arena entrance atrium on Techwood Drive near the CNN Center portals. A goal net from the Omni is displayed in the Philips Arena gift shop.
