欧洲河流：七条具有建筑历史的河流

London is undoubtedly one of the world's greatest cities. With a population of nearly eight million, it is by far the largest city in Europe, spreading over an area of more than 620 square miles. In addition to numerous monuments from its past as a world empire, London is equally known for its pageantry and tradition. Though the city was heavily damaged during the Blitz of World War II, a surprising number of monuments were miraculously spared from destruction. Soon after the end of the war, England's capital began to prosper as never before. London has something for everyone - wide boulevards buzzing with excitement far into the night, quiet squares and explorable alleyways. Large expanses of greenery, such as Hyde Park, Green Park and St. James Park, are all within a few minutes' walk of the West End shops.The museums and galleries are as varied and rich as you will find anywhere. Monuments run the gamut from Roman ruins to sumptuous castles and opulent public buildings, representing the architecture of the triumphal British Empire. Many of these buildings were constructed in the 18th century and during the reign of Queen Victoria to reflect the city's status as the financial and administrative hub of a great empire. Today, London wears its 2,000 years of history with dignity. Alongside modern skyscrapers are remnants of the city's Roman wall. Norman London is evident in one of London's best-known landmarks, the Tower of London, whose origins date back to William the Conqueror.The city's oldest pub, a few medieval churches and the timbered Elizabethan façade of Staple Inn recall London before the Great Fire of 1666. Stately Georgian squares from the 18th century are preserved in the fashionable West End.

Nantes, a city on the Loire River in the Upper Brittany region of western France, has a long history as a port and industrial center. It's home to the restored, medieval Château des Ducs de Bretagne, where the Dukes of Brittany once lived. The castle is now a local history museum with multimedia exhibits, as well as a walkway atop its fortified ramparts.

The capital of Portugal, Lisbon is a city open to the sea and carefully planned with 18th-century elegance. Its founder is said to be the legendary Ulysses, but the theory of an original Phoenician settlement is probably more realistic. Known in Portugal as Lisboa, the city was inhabited by the Romans, Visigoths and, beginning in the 8th century, the Moors. Much of the 16th century was a period of great prosperity and overseas expansion for Portugal. Tragedy struck on All Saints' Day in 1755 with a devastating earthquake that killed about 40,000 people. The destruction of Lisbon shocked the continent. As a result, the Baixa (Lower City) emerged in a single phase of building, carried out in less than a decade by the royal minister, the Marques de Pombal. His carefully planned layout of a perfect neo-classical grid is still evident and remains the heart of the city.There are still remains of pre-quake Lisbon in the Belйm suburb, which survived the destruction, and the old Moorish section of the Alfama sprawling below the Castle of St. George.

Seville is the capital of southern Spain’s Andalusia region. It's famous for flamenco dancing, particularly in its Triana neighborhood. Major landmarks include the ornate Alcázar castle complex, built during the Moorish Almohad dynasty, and the 18th-century Plaza de Toros de la Maestranza bullring. The Gothic Seville Cathedral is the site of Christopher Columbus’s tomb and a minaret turned bell tower, the Giralda.
