Plympton Castle in Devon originated as a Saxon fortification before its transformation into an early 12th-century Norman motte and bailey castle. Established around 1100 by Richard de Redvers or his son Baldwin, the castle changed hands following a siege in 1136 and was subsequently rebuilt in 1141. The Crown ultimately claimed Plympton in 1539, ending centuries of baronial control. Today the castle survives as a distinctive circular mound surrounded by a ditch, crowned with the remains of a stone shell keep, set within a small park in the heart of Plymouth. Its free, year-round accessibility makes it a valuable window into Norman defensive architecture.
