London was founded as a communication center by the Romans shortly after they invaded Britain in 43 AD.
Londinium, as it was called then, was a little village on the Thames., on the route to the provincial capital in eastern England. The Romans built a bridge across Thames on that route, the first bridge on the Thames near the little village. London had narrow, congested streets lined with tiny shops and houses built of wood and plaster back then.
Even the London Bridge, which was considerably more than just a river crossing, had this tendency of narrow, crowded spaces. Therefore, a new stone bridge was built in 1176 to replace the old one. The city of London grew, and so did its population; by 1600 there were 200.000 souls, by the end of the 17th century shot up to 575.000, surpassing Paris as the largest city in Europe. Thus, London became the biggest city in Europe. It also became a cultural center , the center of the English cultural Renaissance, with major figures as Christopher Marlowe, Ben Jonson, William Shakespeare. London was Britain’s economic powerhouse and the center of a burgeoning empire.
