Biggleswade Castle

Biggleswade Castle was a ringwork and bailey castle in the market town of Biggleswade in Bedfordshire. The site was found by aerial photography in 1954 and partly excavated in 1962 and 1968. Excavations uncovered timber structures and pottery fragments. It stood along a major road in the Ivel Valley to control trade and travel. The castle dates from the 12th century and once had a central circular flat surrounded by two deep ditches. Two baileys extend west from the main ringwork, each with its own ditch. A smaller ring ditch on the southern bailey may have been a funerary monument. Today only cropmarks and slight earthworks remain after centuries of farming. The land was altered by agricultural activity over many years. The site is protected as a Scheduled Monument, first listed in 1966. Visitors see faint earthworks and crop patterns marking the castle’s former layout. The central flat and surrounding ditches are still visible in dry weather. The western baileys stretch out with their ditch lines faintly traced. The southern bailey holds the smaller ring ditch, still recognisable in the field. The site lies in open countryside near the town’s edge. It offers a quiet place to imagine the castle’s past role in controlling the valley road.
