The senatorial conference building, also referred to as the New Republic Senate conference building, was situated within the senatorial complex on Hosnian Prime, the world serving as the capital for the New Republic. This edifice featured numerous chambers suited for a wide array of supplementary activities, such as celebratory feasts, prize-giving events, and remembrance recitals.
During the year 28 ABY, the Amaxine warriors, a paramilitary group, executed a bombing of the conference building. Nevertheless, Princess Leia Organa received a warning note scribbled on a napkin during a morning meal, which enabled the senator to trigger the building's warning system and clear the premises prior to the detonation. Because of her actions, there were no fatalities; however, several hundred individuals sustained injuries.
