Anglo Saxon architecture refers to the style of construction that was used by the Anglo Saxons in Britain from their arrival in Britain during the 5th century until the Norman invasion of England in the 11th century.
During this period, Anglo Saxons constructed a large number of secular as well as ecclesiastical buildings. While the secular buildings constructed by the Anglo Saxons were rather simple, their style of architecture is well reflected in the ecclesiastical buildings built by them, few of which are extant to this day.
The secular buildings constructed by the Anglo Saxons had a relatively simple architecture. They usually comprised of timber posts used as boundary walls upon which was supported a large thatched roof. A distinct feature of secular Anglo Saxon buildings was the sizable town hall which was a regular part of most Anglo Saxon towns and a focal point of the community.
Ecclesiastical Anglo Saxon architecture has a more complex history. Anglo Saxons constructed a large number of ecclesiastical buildings and since some of these buildings are all that remain of the Anglo Saxon architecture, they tend to define the style of the Anglo Saxons.
Early Anglo-Saxon churches were built with influences from the local Roman and Celtic populations. Anglo-Saxon buildings of this period typically included a basilica. The use of a tower accompanying the building of a Church or parish is also one of the regular features of Anglo Saxon architecture.
From 8th to 10th centuries, the Anglo Saxon architecture blossomed with possible influences from the European mainland such as from the Carolingian Empire. This period is marked by the use of Romanesque elements in Anglo Saxon architecture. However, few buildings of the period are extant today during to the continuous Viking raids on English shores, many of which were aimed at churches in search for precious loot.
