This hulking construction is the largest building on the Roman Forum. Started by the Emperor Maxentius and finished by Constantine in 315, it originally covered an area of approximately 100m by 65m. Currently, the Basilica is closed to the public due to construction work on Rome's new metro line C.
A colossal statue of Constantine, pieces of which are on display at the Capitoline Museums, was unearthed at the site in 1487.
