There are wonderful sights to view all around Tower Bridge, too. It is one of the most interesting parts of London. On its south side are many tall and old buildings. They are warehouses which hold goods that is shipped to London and waiting to be sold. On its north side stands the Tower of London itself.
    Although they look like the same age, the Tower is more than a thousand years old, and Tower Bridge is over one hundred. It was built in the 1890s. By 1850, everyone disagreed that a bridge across the Thames near the Tower was most necessary. Therefore the designers argued about the new bridge within another thirty years. They took so long because they had two big problems. The new bridge must look like the Tower--everybody said so. It must not look like a modem bridge. But because of the tall ships, it was necessary to have a modern bridge. At last two very clever designers had the idea of an opening bridge. They made it look like the old Tower. All the tall ships can easily come and go. Everyone was so happy.
