Discovery Beneath the Streets
In 1971, construction workers preparing for Doncaster's Inner Ring Road made an extraordinary find. Excavations near St George's Minster unearthed a Roman shield buried within bonfire remains, preserved by fire for nearly two millennia. Archaeologists from the Ancient Monuments Laboratory in London, led by Leo Biek, recovered the fragile artifact by encasing it in a plaster block weighing 1,500 kilogrammes.
The discovery offered a rare glimpse into Doncaster's Roman past as Danum, a strategic fort established during the Vespasian era between 69 and 79 AD.
A Remarkable Survivor
The Danum Shield represents one of fewer than ten Roman shields ever found by archaeologists, making it an exceptional artifact that transforms understanding of Roman military equipment in Britain.
Dating to the late first or early second century CE, the rectangular shield measures approximately 1.25 metres in length and 0.65 metres in width. Its flat profile distinguishes it from the curved scutum shields typically associated with Roman legionaries. The shield's thickness of around 10 millimetres and a reconstructed weight of approximately 9 kilogrammes suggest substantial protective capability.
Construction and Materials
The shield's sophisticated three-layer wooden construction reveals advanced Roman craftsmanship. The central layer comprises six oak staves, each 3.8 millimetres thick and oriented vertically. These are sandwiched between outer layers of alder staves, 3.2 millimetres thick, arranged horizontally. Each stave measures between 103 and 110 millimetres in width.
Both faces were covered in leather, possibly from a single cow hide. The outer surface featured decorative bronze sheeting, which may have been incised with Celtic patterns. Bronze studs of 5 and 8 millimetres diameter, with both flat and domed heads, secured the metalwork. Iron studs of 10 millimetres diameter protruded 6 millimetres from the surface, adding both decoration and defensive capability.
Fittings and Function
The iron shield boss spans 200 millimetres in diameter and stands 2 millimetres thick, positioned 50 millimetres above the centre. A vertical iron handgrip, measuring 0.8 metres long and bound with leather, was secured by six iron rivets. An iron ferrule at the handgrip's end likely accommodated a leather shoulder strap. A wooden rib known as a spina ran vertically down the centre face, measuring 28 to 33 millimetres wide, though serving no structural purpose. Evidence of repairs to the handgrip suggests the shield saw active service.
Cavalry or Infantry: The Enduring Debate
The shield's unusual vertical handgrip has sparked decades of scholarly debate regarding its intended use. Archaeologist Paul Buckland, who published the initial analysis in 1978, suggested the vertical grip indicated cavalry use, though he acknowledged the shield's weight exceeded known cavalry examples.
More recent analysis by Travis and Travis in 2014 proposed an alternative interpretation: the handgrip may have been horizontal, which would suggest infantry use instead. Buckland initially considered whether the shield might be Gallic in origin, perhaps a trophy, but ultimately concluded it was Roman.
Similar rectangular shields have been recovered at Trimontium fort in the Scottish Borders and near Strasbourg in France, suggesting this design was not unique to Danum.
Roman Doncaster: The Fort at the River Crossing
The Danum Shield anchors Doncaster's identity to its Roman origins. The settlement grew around a fort constructed at a strategic River Don crossing, providing an alternative land route between Lincoln (Lindum) and York (Eboracum). The Antonine Itinerary, a second-century Roman road guide, lists Danum on Routes 7 and 8 of the York-to-London route.
The fort was abandoned when Roman forces campaigned in Caledonia under Governor Gnaeus Julius Agricola between 77 and 85 AD. After 87 AD, the fort was reconstructed to house a larger garrison withdrawn from Scotland. The timber fort of the Flavian and Hadrianic periods was later replaced by a stone construction during the Antonine era.
The garrison unit, recorded in the early fifth-century Notitia Dignitatum, was the Crispinian Horse (equites Crispiani). Archaeological evidence suggests the fort occupied the site now occupied by St George's Minster beside the River Don.
Disposal by Fire
The shield lay on a north-south orientation within bonfire remains, partially turned to charcoal through pyrolysis. Archaeologists believe the shield was deliberately disposed of around 105 AD, coinciding with the Roman army's withdrawal from Caledonia. The bonfire context suggests ritual destruction or practical disposal of military equipment no longer required.
Where to See It Today
The iron boss, handgrip, and surviving bronze and iron fragments are displayed at the Danum Gallery, Library and Museum in Doncaster. A reconstruction completed in 1978 accompanies the original components, allowing visitors to appreciate the shield's full appearance.
The artifacts were transferred to this purpose-built facility in 2020 from the former Doncaster Museum and Art Gallery on Chequer Road, which had housed the collection since 1964. The new ยฃ14 million building opened to the public on 29 May 2021, providing modern climate-controlled conditions for preserving this remarkable piece of Doncaster's Roman heritage.
