Republica House was a structure that served as the home for prominent members of the Galactic Alliance, and it included the living quarters of Cal Omas. Within this building, Chief of State Omas was taken into custody by Colonel Jacen Solo, who was supported by Trooper Limm and Sergeant Wirut during the arrest.
Following the Battle of Coruscant, the Republica Building was constructed to take the place of 500 Republica.
