The dam is the largest operating hydroelectric facility in terms of annual generating capacity, generating 94.7 TWh in 2008 and 91.6 TWh in 2009, while the annual generating capacity of the Three Gorges Dam was 80.8 TWh in 2008 and 79.4 TWh in 2009. It is a binational undertaking run by Brazil and Paraguay at the Paraná River on the border section between the two countries, 15 km (9.3 mi) north of the Friendship Bridge. Panama Canal Date started:January 1, 1880 Date finished:January 7, 1914 Location:Isthmus of Panama The Panama Canal is a 77 km ship canal in Panama that joins the Atlantic Ocean and the Pacific Ocean and is a key conduit for international maritime trade. Built from 1904 to 1914, annual traffic has risen from about 1,000 ships in the canal's early days to 14,702 vessels in 2008, measuring a total 309.6 million Panama Canal/Universal Measurement System

Foreword Bridging rivers, gorges, narrows, straits, and valleys always has played an important role in the history of human settlement. Since ancient times, bridges have been the most visible testimony of the noble craft of engineers. A bridge can be defined in many ways, but Andrea Palladio, the great 16th century Italian architect and engineer, hit on the essence of bridge building when he said "...bridges should befit the spirit of the community by exhibiting commodiousness, firmness, and delight." In more practical terms, he went on to explain that the way to avoid having the bridge carried away by the violence of water was to make the bridge without fixing any posts in the water. Since the beginning of time, the goal of bridge builders has been to create as wide a span as possible which is commodious, firm, and occasionally delightful
might have taken place in the year 1892, but actually, the two men never did meet. A copy of the sculpture was given as a gift from the town of Tartu to the Irish city of Galway in 2004. Father and Son The bronze sculpture, "Father and Son", created by sculptor Ülo Õuna (1944-1988), was placed on Küüni Street, on Children's Day ('childrens protection day'), 1 June 2004. Bridges Tartu Stone Bridge In the 18th century the first stone bridge in the Baltics was built at the end of the Town Hall Square, with two triumph arches and a lifting centre, which was dedicated to Catherine II and was opened for traffic in 1784. The bridge was destroyed in World War II, now it can only be admired by way of the model bridge, which was created in 2004. Tartu was hit by a great fire in 1775, during the course of which a large part of the city center burned down. Catherine II
The White Tower, called so on account of the white Caen stone Brought from Normandy, is the original Norman stronghold. It is the central building of the Tower of London. The white tower has three small square towers and one round one. Later other buildings were added. It has served as a palace as well as a fortress, but it is as a prison that it is known best. Many people have been locked in the Tower, for religious beliefs or suspected treason. Traitors' Gate, set in the southern wall of the Tower, has steps leading down to the river Thames. Countless prisoners, including the future Queen Elisabeth I, were brought to the Tower by barge and went up the steps before being imprisoned for many it was their last moment of freedom before their death. Fortunately, Elisabeth was released from the Tower and later became Queen. Elisabeth's father, Henry VII, made the Tower the feared destination of his enemies
unsuccessful. They made their way to the river Thames and sailed up it. The Romans knew it was important to control a crossing point at the river Thames, so they decided to build a settlement on the north bank. Although small settlements had been built on the banks of the Thames, the Romans were the ones who built the first city. They called their city Londinium. The Roman engineers noticed that the point where the swampy river narrowed would make an ideal crossing point, they built London Bridge. Less than 20 years later the native Iceni tribe, led by Queen Boudicca, rose up against the Romans in revenge for mistreatment and burnt Londinium to the ground. The well disciplined Roman army defeated her forces and Londinium was rebuilt. By AD 100 it had also become the capital of the Roman province. A massive wall was built to protect the city from further attacks. The Roman Empire came under increasing attack across Europe and in AD 410 they retreated.
THE CITY OF LONDON History The City of London occupies one square mile in the middle of the capital. It once made up entire town of London, surrounded by the wall first built by Romans. The Romans also built a bridge over the Thames and there has been one in the same area ever since. The Roman Londinium grew up on the northern side of the bridge. In AD 61 the native Celtic tribe, led by Queen Boudicca, rose up against the Romans. They burnt down Londinium to the ground and killed most of its inhabitants. Roman armies eventually defeated Boudicca and Londinium was rebuilt. At the end of the fourth century AD the Roman Empire began to crumble and the Roman armies were recalled from Britain to defend Rome itself. Once they had left, tribes such as Angles, Saxons and Jutes invaded and settled in from Holland, Germany and Denmark
