London was built by Romans in the place where they first crossed the Ri- ver Thames. They built a city a square mile in size, surrounded it with a wall and called it Londinium. This original sight of London is now called the City of London and is Britain's main financial centre. At that time, about 1000 years ago, the Tower of London was built by William the Conqueror. Tower Bridge was built only in 1894. The City is only a very small part of London. in the eleventh century, Lon- don began to expand beyond the City walls when King Edward the Confessor built a huge abbey at Westminster. Even today, Westminster Abbey and the Houses of parliament, as well as all the shops, cafes, theatres and cinemas of the West End, are in the City of Westminster and not in the City of London. Answer the questions. 1. Who founded London? 2. Why was London built on the River Thames? 3. What area does the City of London cover? 4. What can and what can't we see in the City of London? 5. Was Tower Bridge built at the same time as the Tower of London? 6. Who built it? 7. When was Westminster Abbey built? 8. Where can we find beautiful shops, caf s and theatres?
