A January 2014 study in the Journal of Archaeological Science has found that a trove of skulls unearthed 25 years ago in Britain were likely from vanquished gladiators, war captives or criminals.
The skulls were excavated n the heart of London in 1988 prior to construction, but only analyzed recently. Most belonged to young males, and bore marks of violence, such as this skull, with its healed cheekbone fracture.
The jawbone of an adult male bore marks of dog gnawing, suggesting it was stored in an open pit

The skulls may have belonged to gladiators or criminals executed in a nearby amiptheater. But Roman soldiers also often took the heads of barbarians as "trophies" and displayed them publicly, in places such as Hadrian's Wall.
This isn't the only time that construction has yielded stunning archaeological finds in Britain: the remains of Richard III were found under a parking lot in Leicester.
Other places in Britain suggest gladiatorial combat occurred. For instance, a cemetery in York seems to contain gladiator remains.
