Tower Bridge in London

The Tower Bridge is located in above the River Thames, London. On June 30th, 1894, the Tower bridge was opened by King Edward VII. The design of the Tower Bridge was done by Horace Jones and Wolfe Barry, the bridge was constructed in the year 1894. The Tower Bridge contains two massive towers which are linked together. The bridge stands at a height of 60 meters and the height of each tower is about 43 meters. The middle part of the bridge can be lifted up when huge ships pass through that way. In the past, the bridge was lifted nearly 50 times per day.

Initially, the Tower Bridge was constructed as a level crossing over the River Thames, as the population of London grew, new bridges were constructed. But among all the bridges in London, Tower Bridge is the only one of its kinds. During the construction of the bridge, almost 50 designs were taken into consideration, these 50 designs can be viewed at Tower Bridge Exhibition. Finally, John Wolfe Barry and Horace Jones (architects) designs were chosen. Eight years were involved in the construction of the bridge, about 430 laborers and five contractors took part in the construction. Two enormous pillars were downcast deep into the Thames River and 11,000 tons of steel are used in building the walkways and towers. The towers are then built with Portland stone and granite. The construction of the bridge pictures can be viewed in the Tower Bridge Exhibition.

The Tower Bridge is operated by hydraulic methods. Over six massive accumulators are used in the operation of the bridge. These machines use steam to generate power and the power is fed to the accumulators. Using this energy, the bridge bascules are lifted up to a height of about 86 degrees. But from the year 1976, electricity and oil were used in place of steam. In addition, the bridge also uses navigation system for the signaling of ships and to control the traffic.

Palais du Louvre

Originally a military fortress in the 13th century and rebuilt in the middle of the 16th as a royal palace. Converted into a museum in 1973.

Coliseum

This is the most ancient monument from ancient Rome. Its building began in 7.5. A.D. and was opened in 80 A.D., an opening celebrated with a full day of bloody games during which, according to legend, five thousand animals were killed. This was a gruesome leisure activity for the ancient Romans: prisoners condemned to death were torn to pieces by ferocious beasts, animals were killed by archers and there were fights to the death between “professional” gladiators. The surface area of the Coliseum, which totals about 19,000 square meters, was arranged into four sections, each of which could hold up to 70,000 spectators. The Emperor’s box was placed in the center from where he could decide the gladiators’ fate with a simple hand gesture. The underground area of the Coliseum was used to organize and create the settings for the games, such as how to make the ferocious beasts appear unexpectedly in the arena, bringing them up to the main area with an elevator hoist that was hidden in the sand. In 438, the games were prohibited and the Coliseum was gradually abandoned.
