Two-thousand-year-old Roman arena discovered beneath gallery during routine work
The City of London Corporation has confirmed that London’s only known Roman amphitheatre, discovered beneath the Guildhall Art Gallery during construction work in 1988, represents a genuinely striking example of what staff describe as “the City storing its history the way most households store things in the loft,” namely out of sight, largely forgotten, and rediscovered only when someone happens to go looking for something else entirely.
“Nobody knew it was down there,” said a City heritage officer. “Nearly two thousand years, completely undiscovered, right beneath a working gallery. It was found essentially by accident during routine building work, very much a case of ‘well, while we’re down here.'”
The amphitheatre, dating to around AD 70 and expanded in stone during the 2nd century, once hosted gladiatorial combat, animal fights, and public executions for the Roman settlement of Londinium, with capacity estimated to have accommodated several thousand spectators at the venue’s peak period of use.
The amphitheatre’s outline is marked in dark paving stones across Guildhall Yard directly above the underground remains, allowing visitors walking across the square to trace the arena’s original footprint at street level, with the only creatures now regularly occupying the marked arena being, according to staff, “pigeons, filling in fairly admirably for the gladiators.”
The site’s discovery led directly to a redesign of the Guildhall Art Gallery’s rebuilding plans, incorporating a dedicated underground viewing area allowing visitors to see the surviving amphitheatre remains as part of the gallery’s overall visitor experience.
Lighting within the underground display area uses glowing outlines to suggest the presence of Roman-era crowds and structures no longer physically present, a curatorial technique designed to help visitors visualise the space’s original scale and atmosphere with, staff note, “considerably less actual bloodshed than the original venue ever managed.”
Free entry to the amphitheatre remains part of the Guildhall Art Gallery’s wider admission policy, a pricing structure staff point out differs rather significantly from Roman-era entertainment, which, by most historical accounts, “generally cost you a lion, one way or another.”
The discovery has informed ongoing archaeological understanding of Roman London’s civic and social structure, with the amphitheatre’s location and scale providing historians with valuable evidence regarding the size and organisation of the wider Roman settlement.
Guided tours of the underground remains are offered alongside standard gallery visits, with volunteer guides trained specifically in the site’s archaeological history.
