Erected in 184 BC near the Curia Hostilia by Cato Censorius, financed from public funds (Plut. Cato mai. 19, 3; Plut. Cato min. 5, 1), Rome's oldest basilica. When Clodius was killed in 52 BC and his followers turned the Curia into his funeral pyre, the Basilica Porcia burned down as well. Two substructural rooms in opus incertum possibly stem from the Sullan building phase; they are located directly on the Clivus Lautumiarum (Clivus Argentarius) across from the carcer.
