Historical Background.
In 877 the eastern half of England was controlled by the Great Army (of the Danes), Northumbria was colonized and Mercia was reduced to a puppet kingdom. Wessex on the other hand had retained freedom by a combination of bribes and resistance but in January 878 it was overrun by an unexpected winter attack. And so the King, Alfred son of Aethelwulf, had to find sanctuary in the marches around Athelney in Somerset.
From there Alfred waged a guerrilla war, his example plus the morale boosting capture of the raven banner of Ragnar Leatherbreeches enabled Alred to raise another army in the early summer and at Edington in Wiltshire inflicted a major defeat on the Danes. And at the Viking Fortress at Chippenham after a two week blockade by Alfred and his forces the Vikings surrendered, agreeing to leave Wessex and also to having the leaders baptized as Christians. This was a major turning point in the war but there was little chance of rest since remnants of the Great Army still held much of England, while still another force of Danes threatened from across the Channel.
Alfred set about strengthening his position by creating a royal navy and instigating a program of fortress construction consisting of fortifications called burhs. The burhs (later 'boroughs') acted as a form of national defence system, each burh intended to house the people from the surrounding country side during enemy raids. The villages in the area of a burh were required to provide manpower for the defence and maintenance of that burh, on the basis of one man for each hide of land the village contained. Each man was responsible for repairing and defending about 1.25 metres of wall. The number of hides assigned to a burh did vary with the size of the fortification.
Description.
The three main types of burh constructed were; firstly, based on repaired Roman fortifications such as Bath, Exter and Portchester; the second type was based on the promontory forts of the Bronze Age, where and earthwork rampart was raised across a steep sided headland, such as at Lydford in Devon, Christchurch in Hampshire and Burpham ins Susses; the third type's defences consisted of a surrounding earthen rampart which was faced with wood or stone, the rampart was fronted by a deep ditch. In some cases the area inside these walls were divided up into plots in gridwork for residental purposes, that layout still exists at Wareham and Wallingford.
Other Relevant Information.
At the end of Alfred's reign in 899 England was a lot safer from Viking raids, his son King Edward ahd his daughter Aethelfleda continued the work. Their new burhs were constructed to consolidate their territorials gains at; Hertford, Bedford, Buckingham, Stamford and Nottingham.
