Leaning Tower of Pisa is one of the most unusual wonders of the world. It is known for its leaning position. Many of us are still in confusion regarding its shape, right? It's strange to believe how engineers are working to find ways to make it straight when we are still confused about its shape. Standing at the height of 186 feet, Leaning Tower of Pisa is straightened by engineers now after the efforts of many years. In the year 1990, this tower was closed to the public because of safety issues.
Roberto Cela, a famous engineer stated in an interview that many tubes are put by the team of engineers to protect the tower from leaning down. Some other notable persons in the engineering field took up a study of this tower and stated that the tower has begun to straighten by 4 centimeters from the year 2001. They further said that the tower leans less in hot summers. This is because the warm temperature causes the stones to expand which further straightens the tower. This fact is stated by the engineers only and not by tourists. Some of the tourists who visited this tower didn’t find much difference.
