A Famous Tower in Italy
The Leaning Tower of Pisa is located in Italy, in the city of Pisa in the region of Tuscany. It is one of the most recognisable buildings in the world and has become an architectural symbol of Italy itself.
A Bell Tower That Tilts
The tower was not designed to lean. It is actually the bell tower, or campanile, of Pisas cathedral. Construction began in the twelfth century, but the ground beneath it was soft and unstable. Before even the upper floors were finished, the structure had begun to tilt to one side - and the famous lean was born.
Centuries of Careful Work
Building the tower took almost two centuries, partly because work was halted for long periods, which may accidentally have helped the soft ground settle and kept the tower from collapsing. Over the centuries the lean slowly grew worse, until major engineering work in modern times reduced the tilt and stabilised the structure. Today the tower stands safely and welcomes millions of visitors every year.
