The Greek historian Herodotus once made a list of the most extraordinary structures in the

world, which was known as the Seven Wonders of the Ancient World. Swiss explorer Bernard Weber thought the old list needed updating. He wanted everyone to vote for the worlds cultural treasures. In 2001, the New Seven Wonders Foundation was set up, inviting people around the world to vote. A group of building experts later reduced the list to 21 places. From 2006 to July 6, 2007, people around the world voted on their favorite places by using the Internet and cell-phones. There were about one hundred million votes in all. The results were announced on July 7 in a ceremony in Lisbon, Portugal. Here is the new list of world wonders. The Great Wall of China is one of the largest building projects on earth, extending for over 7 000 kilometers and built to defend against foreign invaders. The oldest parts of the wall were built over 2 600 years ago. More recent parts were built about 500 years ago. The emperor Qin Shihuang created the first united China about 2 200 years ago and connected the different parts of the wall into one huge system. Chiehen Itza is a temple city built by the Mayans over 1000 years ago in what is now Mexico. Many large stone structures were built during different periods with different styles. One holy building is a triangular-shaped(三角形的)step pyramid called the Temple of Kukulean. This huge structure has a staircase on each of the four sides that leads to the religious altar(祭坛)at the top. There are many other temples and even a large court area where the Mayans played ball games. Christ the Redeemer(基督像)is a large religious statue on a hill overlooking the city of Rio de Janeiro, Brazil. Catholic religious leaders in the city started planning the project in the 1920s. This 38 meter statue of Jesus was completed in 1931. It is made of concrete and soapstone materials. Christ the Redeemer was designed by the Brazilian engineer Heitor da Silva Costa and the French sculptor Paul Landowski.
