Julius Caesar invaded Britain in 55 BC, but it was really conquered only by Emperor Claudius in the years 43-47 AD.
One of the first things the Romans did was involving the conquered people to the administration of the province encouraging the growth of towns near their army bases.
Most towns were surrounded by stone walls and contained a network of streets. At the centre of the town there were the forum and the basilica, which were the civic centre and the town hall; and public baths. The towns were joined by amazingly well built streets, which made movements easier. The most important monument made by Romans in Britain was Hadrian’s Wall.
London’s origins can be dated to 43 AD Roman’s invasion, when a bridge was built across River Thames. It soon became the centre of the new network of roads who spreader from it. The Roman settlement on the north side of the bridge, called Londinium, quickly became important as a trading centre for goods.
Hadrian’s Wall is a defensive fortification built after Emperor Hadrian’s visit in 122 AD. It is 73 miles long, 8-10 feet wide and 15 feet high. The Romans also built a system of small forts, the milecastles, which housed up to 60 soldiers and were placed one every mile. Sixteen larger of them were built into the wall, which housed a major number of soldiers. The best-known of them is now a museum that shows how was the soldiers’ life.
