Lakenna--Leaning+Tower+of+Pisa

Famous leaning tower of Pisa  The leaning tower of Pisa is an important place because it was suppose to standing straight, but it started leaning during construction. It was built to show the rest of the world the wealth of the city of Pisa. The city of Pisa was a successful trading center and the tower was designed to be a compliment to the city’s cathedral. A lot people tried to get used to the tower being slanted but they can’t.  The leaning tower of Pisa took nearly 2 centuries to get finished. The construction work began August 9th, 1173 and ended in 1372. In 1178 they stopped working on it because it started to sink in the ground after it reached the third floor of construction. It was stopped for about 90 years and then completed by Tommano Simone and Giovanni Di Simone.  Recently they put some weights in the bottom floor to try and keep it from falling. Also after ten years of tower rehabilitation its ancient key was ceremonially handed back to the church guardians. In February 1999, engineers begin a process of soil extraction. They removed underlying soil at an extremely conservative pace of about five gallons every two days. In mid- June, the tower was leaned back toward the north by 90 arc seconds.  People are starting to think that the tower of Pisa is slowly sinking into the ground. Lately it seems like the tower has been missing 1mm of its parts every single year. Nobody knows just yet if this will continue on in the future. They will have to find someone that can be able to state the actual facts by scientific studies but in the mean time supervision with instruments that are made of very high precision is being carried out.  While the tower of Pisa is still leaning, in 1990 the Italian government decided to close it down. In 1996 engineers successfully complete a test of a soil-extraction method to reduce the tower’s lean. The method calls for an inclined drill, however the actual soil does not get underway for almost three years. After that the engineers installed temporary cables. In 1999 the restarted the whole soil-extraction process all over again.  Geis, Darlene. Let’s travel to Italy.
