Prehistory In 1993, remains of a Bronze Age bridge were found on the south foreshore upstream from Vauxhall Bridge.[44] This either crossed the Thames or reached a now-lost island in it. Two of the timbers were radiocarbon dated to 1750–1285 BCE.[44] In 2010, foundations of a large timber structure, dated to 4800–4500 BCE,[45] were found on the Thames's south foreshore downstream from Vauxhall Bridge.[46] The function of the mesolithic structure is unclear. Both structures are on the south bank of the Thames, where the now-underground River Effra flows into the Thames.[46] Roman London Main article: Londinium
In 1300, urban area of the City was still largely confined within the Roman walls.
Despite the evidence of scattered Brythonic settlements in the area, the first major settlement was founded by the Romans about four years[2] after the invasion of 43 AD.[47] This only lasted until about 61 AD, when the Iceni tribe led by Queen Boudica stormed it and burnt it to the ground.[48] The next planned incarnation of Londinium prospered, superseding Colchester as capital of the Roman province of Britannia in 100. At its height in the 2nd century, Roman London had a population of about 60,000.[49] Anglo-Saxon and Viking-period London With the early 5th-century collapse of Roman rule, London ceased to be a capital and the walled city of Londinium was effectively abandoned, although Roman civilisation continued around St Martin-in-the-Fields until about 450.[50] From about 500, an Anglo-Saxon settlement known as Lundenwic developed slightly west of the old Roman city.[51] By about 680 the city had become a major port again, but there is little evidence of large-scale production. From the 820s repeated Viking assaults brought decline. Three are recorded; those in 851 and 886 succeeded, while the last, in 994, was rebuffed.[52]
The Lancastrian siege of London in 1471 is attacked by a Yorkist sally.
The Vikings applied Danelaw over much of eastern and northern England, its boundary running roughly from London to Chester as an area of political and geographical control imposed by the Viking incursions formally agreed by the Danishwarlord, Guthrum and the West Saxon king Alfred the Great in 886. The Anglo-Saxon Chronicle records that Alfred "refounded" London in 886. Archaeological research shows this involved abandonment of Lundenwic and a revival of life and trade within the old Roman walls. London then grew slowly until a dramatic increase in about 950.[53] By the 11th century, London was clearly the largest town in England. Westminster Abbey, rebuilt in Romanesque style by King Edward the Confessor, was one of the grandest churches in Europe. Winchester had been the capital of Anglo-Saxon England, but from this time London became the main forum for foreign traders and the base for defence in time of war. In the view of Frank Stenton: "It had the resources, and it was rapidly developing the dignity and the political self-consciousness appropriate to a national capital."[54][55]
