<span>Leaning Tower of Pisa in Italy was constructed as the bell tower for the city's cathedral. However, at that time the architects weren't experienced. So, it was built on soft ground and as soon as it had been built, it slowly began to lean.
Over the years, many attempts were made to stop the tower from leaning. Once, people removed stones from the bottom in order to put strong metal rods in, but the stones that were being removed were part of the foundations so the tower leaned even more! Since then it has been reinforced to correct this. Today, the tower can still be seen leaning to one side. It is covered in marble and it is very beautiful. Unfortunately, however, it was closed to the public in 1990 after it was revealed that a single busload of tourists at the top could make it fall over completely! All the same, it will be visited by tourists for many years to come.</span>
