Prehistoric Lincolnshire (to c. AD 43)

From flint tools to a tribal mint and economy.

What is Prehistoric Lincolnshire best known for?

Prehistoric Lincolnshire is known for its wetland engineering, salt production, and complex tribal economies. Its historical significance comes from pioneering landscape adaptation and commerce. From Neolithic long barrows to the massive Iron Age coin mint at Old Sleaford, its people transformed a volatile wilderness into a prosperous, interconnected trade hub long before Roman conquest.

Prehistoric Lincolnshire: Frequently Asked Questions (FAQs)

Why are there so few visible prehistoric monuments in Lincolnshire?

Much of the county's early history is hidden. Centuries of intensive farming, draining the Fens, and layers of marine silt have buried or destroyed ancient earthworks. This makes modern aerial photography and infrastructure digs critical for finding sites.

What did the famous Fiskerton logboats reveal about Iron Age life?

Discovered in the Witham Valley, these well-preserved timber boats proved that ancient communities were highly skilled navigators. The boats, alongside deliberately damaged weapons, show the river was used for high-status ritual offerings to water deities.

Where did Lincolnshire's earliest humans live?

Evidence of human life goes back over 300,000 years. Early hunter-gatherers left behind Palaeolithic flint tools deep within glacial gravels, particularly around areas like the Lincolnshire Wolds.

What was the significance of the Lincolnshire Wolds in the Bronze Age?

The Wolds served as a major territory and burial landscape. The area contains nearly 60 Neolithic long barrows and over 350 Bronze Age round barrows, which were used to bury elite tribal members alongside prized grave goods like pottery beakers.

How did prehistoric communities use Lincolnshire's coastline?

During the Bronze and Iron Ages, the coast was a bustling industrial zone. Ancient communities established sophisticated salt-making sites (salterns), filtering seawater to produce salt, which was a highly valuable commodity for preserving food and trading across Britain.

  3. c. 8500 BC
    Hunter-gatherers establish camps

    Mesolithic communities create seasonal camps along the River Witham, mastering the landscape to hunt, fish, and gather resources.

  4. c. 4000 BC

    These massive earthen tombs anchor communities to the land, serving as sacred burial places for their ancestors.

  6. c. 2500 BC
    Beaker culture arrives

    Migrants from continental Europe introduce metalworking and new beliefs, shifting burial customs to individual round barrows.

  7. c. 2500 BC
    Crowland Henge is built

    This enormous circular earthwork creates a major ceremonial centre for tribal gatherings and rituals in the southern fens.

  8. c. 800 BC
    The Brigg Raft is constructed

    This sophisticated, flat-bottomed boat demonstrates advanced woodworking and the growing importance of river-based trade.

  9. c. 800 BC
    The Iron Age begins

    New technology drives an industrial boom in salt-making along the coast and allows for denser, more organised settlements.

  10. c. 300 BC
    The Witham Shield is crafted

    This masterpiece of Celtic art, recovered from the river, represents a high-status ritual offering to the gods of the water.

    The arrival of Roman legions ends prehistory and triggers the construction of a major imperial fortress at Lincoln.

Brief History

The drowned lands (c. 500,000–4000 BC)

Glaciers carved the physical foundations of Lincolnshire, leaving a frozen desert that melted into a dynamic, shifting wilderness. As the ice retreated, rising meltwaters choked the North Sea basin, eventually severing the land bridge to continental Europe.

The early nomadic communities who trod this landscape did not find a stable county, but a volatile expanse of waterlogged fen and chalk uplands. Human survival depended entirely on following the seasonal rhythms of the wild.

On the high, dry ground of the Lincoln Edge — the prominent limestone ridge running north to south through the county — family groups tracked game and gathered resources. Excavations on the banks of the Brayford Pool revealed a Late Mesolithic hunting camp, providing physical evidence of these early settlers working flint and processing meat on the edge of what would become the River Witham.

The First architects (c. 4000–2200 BC)

The introduction of agriculture transformed Lincolnshire from a landscape that humans merely inhabited into one they actively reshaped. Communities began clearing the dense wildwood, establishing permanent roots in the fertile soils of the Wolds.

This shift from foraging to farming required a new relationship with the earth, marked by the construction of monumental earthworks. Mortal remains became anchors for territorial claims.

At Giants Hills near Skendleby, Neolithic farmers piled earth and timber to create massive long barrows, sealing the bones of their ancestors into the landscape. These people were not isolated; the discovery of a beautifully polished stone axe head near Lincoln, crafted from greenstone quarried in Cumbria, proves that complex trade routes crossed Britain thousands of years before the first paved roads.

Masters of the water (c. 2200–800 BC)

The introduction of bronze coincided with a changing climate that turned the low-lying Fens into a vast, waterlogged wilderness. Rather than retreating, Bronze Age communities adapted, turning the treacherous waterways into prosperous trade highways.

They mastered the management of the wetlands, utilising timber platforms and advanced watercraft to navigate the sodden landscape. The scale of this aquatic infrastructure became clear during excavations for the Lincoln Eastern Bypass.

This project uncovered a vast riverside ceremonial landscape where prehistoric engineering met spiritual devotion, with timber structures jutting out into the marshes. Further south, the excavation of the Brigg Raft in 1886 revealed a sophisticated flat-bottomed timber boat, engineered specifically to ferry heavy goods and livestock across the unpredictable Humber estuary, anchoring the region within wider British trade.

Iron, salt, and sacrifice (c. 800–100 BC)

As the climate cooled further, the marshlands expanded, driving a boom in two distinct but connected activities: heavy industry and ritual sacrifice. Along the edge of the Fens, at sites like Horbling, communities established a massive salt-making industry.

Crouched over suffocating hearths, common labourers boiled brine in coarse earthenware vessels, enduring gruelling physical labour to produce a vital preservative that fuelled trade across the region. Simultaneously, the dark waters of the River Witham became a focus for tribal spirituality.

At Fiskerton, a timber causeway was maintained for generations, acting as a platform for ritual deposition. Tribesmen cast high-status weaponry into the peat-stained waters to appease their gods, a practice epitomised by the Witham Shield, a masterpiece of prehistoric metalwork retrieved from the river mud where it was cast.

The tribal mint (c. 100 BC–43 AD)

In the final centuries before European integration, Lincolnshire was dominated by the Corieltauvi, a loose confederation of agricultural tribes. Far from being a chaotic frontier, Late Iron Age Lincolnshire possessed an organised economy, a structured hierarchy, and international connections.

Power shifted toward major proto-urban settlements that controlled trade and manufacturing. Old Sleaford became the economic engine of the region, hosting the largest pre-Roman coin mint in Europe.

Archaeologists discovered thousands of clay pellet moulds used to cast gold and silver currency, proving that the Corieltauvi maintained an intricate monetary system tied directly to continental trade networks. This prosperous, stable tribal landscape lasted until 43 AD, when the first Roman scouts arrived on the banks of the River Witham, eyeing the strategic high ground of the Lincoln Edge for a new imperial fortress.
