Anglo-Saxon architecture was a period in the history of architecture in England from the mid-5th century until the Norman Conquest of 1066. Anglo-Saxon secular buildings in Britain were generally simple, constructed mainly using timber with thatch for roofing. No universally accepted example survives above ground. Generally preferring not to settle within the old Roman cities, the Anglo-Saxons built small towns near their centres of agriculture, at fords in rivers or sited to serve as ports. In each town, a main hall was in the centre, provided with a central hearth.

The Anglo-Saxons were a cultural group that inhabited much of what is now England in the Early Middle Ages, and spoke Old English. They traced their origins to Germanic settlers who came to Britain from mainland Europe in the 5th century. Although the details are not clear, their cultural identity developed out of the interaction of these settlers with the pre-existing Romano-British culture. Over time, most of the people of what is now southern, central, northern and eastern England came to identify as Anglo-Saxon and speak Old English. Danish and Norman invasions later changed the situation significantly, but their language and political structures are the direct predecessors of the medieval Kingdom of England, and the Middle English language. Although the modern English language owes somewhat less than 26% of its words to Old English, this includes the vast majority of words used in everyday speech.
