The leaning tower of Pisa is one of the most famous building in the world. It is famous not because of its beauty size, but because it leans dangerously to one side. Each year the tower attracts thousand of visitors from all around the worldSometimes the tower leans to the south and also curves towards the north. It is said that the tower has leaned more than 17 feet. Over the past years various proposals have been made to stop the tower from leaning westwards and to prevent its collapse. Some people would like to pull it down and rebuild it in stronger foundations. Others have suggested pouring concrete around the base of the tower to stop its from leaning further. If nothing is done, the tower might collapse very soon. But until it is rebuild or straightened, it will remain as one of the most fascinating architectural mistakes in the world17 feet
