The Basilica of Maxentius, also known as the Basilica Nova, is an ancient Roman building located in the Roman Forum. Constructed between 306 and 312 AD during the reign of Emperor Maxentius, it served as a public space for legal proceedings and gatherings. The basilica is notable for its impressive size, featuring a vast central hall and two side aisles, all covered by a magnificent vaulted roof. The structure showcases innovative Roman engineering, particularly in its use of concrete and arches. Although it was partially destroyed over the centuries, the remaining ruins highlight the grandeur of Roman architecture. The basilica is often associated with the transition from paganism to Christianity in ancient Rome.
