Overview
Excavation at Sully Castle uncovered occupation from Roman Britain to the eighteenth century. A twelfth-century earthwork gained a stone keep, then became a fortified manor in the thirteenth and early fourteenth centuries before later loss left only wall fragments near the church.
Who built and held it
No secure named founder can be tied to the earliest medieval phase. Excavation instead shows that a local lord established an earthwork castle in the twelfth century and later added a stone keep as the residence became more permanent.
Attack, change and use
Four medieval phases reveal rebuilding rather than a known siege. During the thirteenth and early fourteenth centuries the earlier stronghold was reshaped as a fortified manor house, and occupation or reuse continued on the site into the seventeenth or eighteenth century.
What survives
The castle was largely destroyed by 1828. Excavations in 1963–69 recovered its buried plan, six phases of use and pieces of painted wall plaster; a wall and gateway fragment remain incorporated near the northern edge of Sully churchyard.
Why it mattered
Sully matters because digging revealed the full change of one site from early occupation to earthwork castle, stone keep, comfortable fortified manor and later use. The painted plaster also reminds us that defence and decorated domestic life occupied the same buildings.
