The Golden Gate Bridge

The Golden Gate Bridge links San Francisco with Marin County in absolute splendor. The bridge is one of the architectural marvels of the Twentieth Century and a testament to human strife, as it was constructed during the years of the Great Depression. For years, the Golden Gate Bridge held the title as the longest suspension bridge in the world.

The North Sea Protection Works

For many, the image out of the Dutch fight against the North Sea rests in the figure of a young boy valiantly saving his town by using a finger to plug a hole in the dike. But this familiar hero is a fictional one, a creation of American author Mary Mapes Dodge in her book, Hans Brinker. In reality, heroism falls on all the Dutch, who for more than a millenium have been wresting precious agricultural lands from the sea and fighting to hold on to them. Their greatest achievement-a colossal fun in the dike-if the vast and one dress project known as

The Channel Tunnel

The Channel Tunnel is considered one of the most amazing engineering feats of the 20th century.

Channel-Tunnel train

The Channel Tunnel is a 50.45-km (31.4 miles) undersea rail tunnel linking Britain and France, under the Strait of Dover in the English Channel. The Channel Tunnel is also affectionately referred to as the Chunnel or Eurotunnel, and in French it is known as ‘Le Tunnel Sous la Manche’. Travel through the Channel Tunnel on a high-speed train takes around 20 minutes, and bypasses the sometimes inclement weather of the English Channel to deposit passengers safely on the other side.

The Panama Canal

Panama Canal

Among the great peaceful endeavors of mankind that have contributed significantly to progress in the world, the construction of the Panama Canal stands as an awe-inspiring achievement. The unparalled engineering triumph was made possible by an international work force under the leadership of American visionaries, who made the centuries-old dream of uniting the two great oceans a reality.

The CN Tower

CN Tower is fitting that television, the technological wonder that profoundly changed life in the 20th century, spurred the building of the era's tallest freestanding structure. In the late 1960's, Toronto's soaring skyline began to play havoc with signals from conventional transmission towers. Signals bouncing off the city's skyscrapers produced a number of problems, including the annoying phenomenon of "ghosting" on television sets.

The Itaipu Dam

The Itaipu hydroelectric power plant is the largest development of its kind in operation in the world. Built from 1975 to 1991, in a binational development on the Paraná River, Itaipu represents the efforts and accomplishments of two neighboring countries, Brazil and Paraguay. The power plant's 18 generating units add up to a total production capacity of 12,600 MW (megawatts) and a reliable output
