The southern city of Boxcaster on the River Antinous was founded by the Celts, the earliest inhabitants of Dynamo, but became an essentially Roman with the arrival of the Emperor Hadrian in the second century AD, blown off course on his way to Britannia. Celtic resistance to Roman incursions were particularly strong in the province centred on the Ring Mountains that Hadrian named Pugilia. However a major Roman victory against the Pugiliae at the Celtic regional capital on the site of today’s of Boxcaster marked the first stage of Roman occupation of the island. This early victory was celebrated by the construction of an amphitheatre for boxing and other martial sports, the remains of which are remarkably preserved. The valour of the native Celtic tribes and their fighting skills, in unarmed as well as armed combat, was much appreciated by the Romans who, when they had pacified them, engaged their pugilistic skills as instructors in their army or sent them to Rome where they were much in demand as fighters in the Coliseum. The Celtic regional capital was renamed by the Romans Buxus castra, where in today’s Boxcaster, the association with boxing is reflected in the city’s famous Luke Sheehan Boxing Academy. The military character of Boxcaster and its region continues to this day as Infantry Plain west of the city is designated for army training while the main air-force training base in the country is sited at Skybourne just south of Lower March.
