How Did Roman Alchester Shape the Origin of Bicester?
The true origin of Bicester begins two miles south of the modern town centre at Alchester. Established in AD 43 during the early stages of the Roman invasion under Emperor Claudius, Alchester served as an important legionary fortress. Roman engineers selected this location because it sat at the strategic intersection of major military roads, including Akeman Street connecting Verulamium (St Albans) with Corinium (Cirencester). Archaeological excavations carried out by Oxford University have uncovered wooden gateposts, defensive ditches, and stone military parade grounds dating from AD 44.
As military operations shifted northwards, Alchester evolved into a walled civilian town with stone townhouses, granaries, and public bathhouses. The settlement thrived for over three centuries, housing soldiers, merchants, and stonemasons. By the 5th century, as Roman imperial administration collapsed across Britain, residents gradually abandoned Alchester. The ruined stone walls provided materials for early Anglo-Saxon settlers who chose higher, drier ground two miles to the north. That new site along the River Bure became the foundation of modern Bicester. Today, you can still walk along the public footpaths near Wendlebury to view the earthworks of the Roman fort, as detailed in our guide to Alchester Roman town.
What Are the Saxon and Medieval Roots of Bicester?
Anglo-Saxon settlers established a permanent village here during the 6th and 7th centuries, naming it Berencestre, meaning Beorna’s fortified place. Around AD 635, King Cynegils of Wessex converted to Christianity under the guidance of Saint Birinus, leading to the construction of a Saxon minster church. That early place of worship stood on the exact site occupied today by St Edburg’s Church. Dedicated to Saint Edburg of Bicester, a 7th-century Saxon princess, the church became a central place of spiritual devotion. If you examine the north wall of the nave inside St Edburg’s, you will see a triangular-headed stone archway, which historians identify as a surviving fragment of original Saxon masonry.
The Norman Conquest of 1066 brought sweeping administrative changes to Bicester. The Domesday Book of 1086 records Bicester as a manor held by Robert d’Oyly, who also constructed Oxford Castle. In 1182, the Norman Lord of the Manor, Gilbert de Basset, founded an Augustinian Priory dedicated to Saint Edburg and Saint Mary. The priory stood near present-day Priory Lane and Chapel Street, housing monks who tended gardens, managed fishponds, and hosted visiting pilgrims. You can explore the fascinating story of these medieval monks in our guide to Bicester Priory history.
A landmark turning point occurred in 1239 when King Henry III granted a royal market charter to William Longespée, Earl of Salisbury, who had married into the Basset family. This charter gave Bicester the legal right to hold a weekly market on Tuesdays, establishing Market Square as the commercial heart of the area. Blacksmiths, weavers, butchers, and wool merchants set up permanent stalls around the triangular square. You can read more about how trade developed over the centuries in our detailed guide to Bicester’s Market Square history. The priory continued to flourish until 1536, when King Henry VIII ordered the Dissolution of the Monasteries, leading to the demolition of the priory buildings and the distribution of its lands to local gentry.
How Did the Railways and Aviation Change Bicester in the 19th and 20th Centuries?
Throughout the 17th and 18th centuries, Bicester maintained its character as a quiet market town famous for sheep farming, lace making, leather tanning, and malting. The arrival of steam transport in the mid-19th century fundamentally altered the local economy. In 1850, the Buckinghamshire Railway opened Bicester Town station (now Bicester Village station), providing direct rail connections to Oxford, Cambridge, and London. One year later, in 1851, the Great Western Railway opened Bicester North station. These railway links allowed local farmers to send livestock and dairy produce directly to London markets within hours, spurring rapid economic growth.
Victorian prosperity left a lasting architectural mark across Bicester. In 1840, Richard Falshaw constructed Garth House, an elegant gothic-style country house surrounded by private gardens off Launton Road. Today, that estate forms Garth Park, which houses the Bicester Town Council offices and provides public parkland for local families. You can discover the full story of this Victorian residence in our historical guide to Garth House and Garth Park.
The 20th century introduced military aviation to Bicester’s landscape. In 1916, during the First World War, the Royal Flying Corps established a military airfield on grass fields north of the town. During the 1920s, the Air Ministry rebuilt the site into a permanent RAF Bomber Command station based on the architectural designs of Archibald Bickerton. During the Second World War, RAF Bicester served as a vital operational training unit, training crews for Blenheim and Mosquito bombers. Today, the airfield is recognized by Historic England as the most complete interwar military station in Britain. The site has been preserved and transformed into Bicester Motion, a world-class hub for historic automotive and aviation engineering. You can explore this military heritage in our feature on RAF Bicester history.
