The Roman amphitheatre of Londinium is situated in a vaulted chamber beneath the Guildhall gallery complex.
Discovered in 1998 during a planned expansion of the Guildhall, the remains are displayed in situ and are now a protected monument.
London’s first Roman amphitheatre was built in AD70, constructed of wood, but was later renovated during the 2nd century with rag-stone walls and a tiled entrance.
Able to hold thousands of spectators, the size of the amphitheater is displayed on street level, where the circumference of the arena is marked with a black circle on the paving of the courtyard in front of the hall.
The amphitheatre was used for various events, including gladiatorial games, animal fighting, executions and religious festivities.
When the Roman province of Britannia looked to its own defences, the amphitheatre became derelict along with the remainder of the Roman city and turned to ruin.
Further Excavations by MOLAS in 2000 at the entrance to Guildhall Yard exposed remains of a great 13th-century gatehouse built directly over the southern entrance to the amphitheatre.
