It was originally known as the LSU Assembly Center, but was renamed in honor of Pete Maravich, a Tiger basketball legend, shortly after his death in 1988.  Louisiana Governor Buddy Roemer signed an act to rename the building in Maravich's honor (under Louisiana law, no LSU or state owned building may be named after a living person).  Maravich never played in the arena as a collegian but played in it as a member of the Atlanta Hawks in a preseason game.  But his exploits while at LSU led the University to build a larger home for the basketball team, which languished for decades in the shadow of the school's football program.  The Maravich Center is known to locals as "The PMAC" or "Pete's Palace", or by its more nationally known nickname, "The Deaf Dome", coined by Dick Vitale.  The Maravich Center's neighbor, Tiger Stadium is known as "Death Valley".
