What is “a burh” in Anglo-Saxon England?

The story behind the answer

Created chiefly under King Alfred and his successors, these defensive urban centers were ringed with ditches, earthen ramparts, and timber (later stone) walls to protect local populations from Viking raids. They housed garrisons, stored supplies, and could be rapidly manned by the local militia (fyrd). The Burghal Hidage, a 10th‑century document, lists many of them and the tax obligations that maintained their defenses.

Over time, these places became administrative hubs and magnets for trade, with markets and crafts flourishing behind their walls. Many later English towns grew from them, often preserving their names in endings like -bury, -borough, or -burgh (e.g., Salisbury, Peterborough). They were not burial mounds (barrows) or monastic communities, but planned, defended settlements.
