This is a picture of the tower of Pisa in Italy
Tower of Pisa is one of the seven wonders of the world which was built in 1178. Construction is tilt but still sturdy stand, despite being more than 8 centuries stood with unusual conditions make the tower with a bell on top of this special. If anyone asks, "Is the tower that this slope is increasing each year could collapse?" The answer is "Yes". Tower of Pisa had nearly collapsed on January 7th, 1990. The management decided to close the tower of Pisa to the public because the slope of the tower is already in the alarming level and is predicted to be collapsed at any time.
Intensive reconstruction was performed immediately in order to preserve the historic monuments that are part of the cathedral in this city of Pisa. All residents who live around the tower were evacuated to prevent the fall, the bells atop the tower was temporarily moved to reduce the burden of the tower. Steel cables were used to maintain the stability of the tower. Reconstruction focused on the overhaul of the foundation which is becoming a major problem. Finally after a period of intensive reconstruction, the Tower of Pisa reopened to the public on December 15, 2001. In May 2008, the engineers ensure that the conditions of the Tower of Pisa will be safe (the slope will not increase) at least for the next 300 years.
History of the Tower of Pisa itself is actually quite unique. The tower was built in four phases and take two centuries. The slope is the main attraction is actually a calculation error, because the foundation is too small and the tower was built on sandy soil. So when the construction reaches the 3rd floor partially collapsed tower and the tower became skewed. After having been suspended for 100 years, eventually building the Tower of Pisa was continued by adding 4 more floors built in the direction "toward the perpendicular" to compensate for the slope. So actually the Tower of Pisa is not only skewed, but also curved.
