The Rialto Bridge is one of the four bridges spanning the Grand Canal in Venice, Italy. It is the oldest bridge across the canal, and was the dividing line for the districts of San Marco and San Polo.
The first dry crossing of the Grand Canal was a pontoon bridge built in 1181 by Nicolò Barattieri. The development and importance of the Rialto market on the eastern bank increased traffic on the floating bridge, so it was replaced in 1255 by a wooden bridge.
During the first half of the 15th century two rows of shops were built along the sides of the bridge. The rents brought an income to the State Treasury, which helped maintain the bridge.
Maintenance was vital for the timber bridge. It was partly burnt in the revolt led by Bajamonte Tiepolo in 1310. In 1444 it collapsed under the weight of a crowd watching a boat parade and it collapsed again in 1524.
The present stone bridge, a single span designed by Antonio da Ponte, was finally completed in 1591.
The Zhangye Danxia landform is also known as the eye candy of Zhangye. This four hundred square kilometer attraction is located in Gansu Province in northwest China and is surrounded by color hills. Geologists believe that danxia are formed as a result of movement in the earth’s crust. This makes rock layers appear in different colors, textures, shapes, sizes and patterns. The combination of these differences creates towering peaks, cave holes and stone halls.
Built between 1967 and 1972, the Nový Most is a road bridge over the Danube and it is the world’s longest cable-stayed bridge to have one pylon and one cable-stayed plane. A special attraction is its flying saucer-shaped structure housing a restaurant.
Since its construction the bridge was called “Most Slovenského národného povstania” (English: Bridge of the Slovak National Uprising), although locally it was called New Bridge. In 1993, its name was changed by the Bratislava city Parliament to Nový Most (English: New Bridge) to unify its official name with the one actually used by the people.

Salar de Uyuni (or Salar de Tunupa) is the world’s largest salt flat at 10,582 square kilometers (4,086 sq mi). It is covered by a few meters of salt crust, which has an extraordinary flatness with the average altitude variations within one meter over the entire area of the Salar. The crust serves as a source of salt and covers a pool of brine, which is exceptionally rich in lithium. It contains 50 to 70% of the world’s lithium reserves. The Salar also contains large amounts of sodium, potassium, magnesium and borax.
The bridge was built between 1904 and 1905, being destructed in 1916 by the Austrians during the First World War to prevent the invading forces from using it. The actual bridge, reconstructed between 1925 and 1927 is very similar to the first one with the exception of having only four sub-arches instead of the original five. During the Second World War the bridge suffered only minimal damage from bomb attacks, which the Germans repaired in a few days. With an arch span of 85 m, it is the second-longest stone arch in the world and the longest stone arch among train bridges.
