Leaning Tower of Pisa is actually a belfry or standalone tower bells of the cathedral in the Italian capital, and is considered the most visited attraction in it. The preparation of the tower began in the 12th century, but the work was soon interrupted because the land beneath it began to sink.
The tower was completed in 1350 and was due to the tilt of the soft soil that was built and because of lax foundations. The total height of the tower is 56 meters and was built after each year began tilting to one millimeter.
However, the most difficult times, survived the Second World War, when almost been demolished. The Allies after entering the city were ordered to demolish all the buildings that could represent the position of the German snipers.
Because of bad weather, as it was very hot, the attack on the tower was delayed, and in the meantime the Germans retreated, so fortunately this piece of world architecture has remained preserved.
The tower was closed in 1990 for safety reasons, and in the decade that followed lasted fight to preserve it. Architects finally managed to “raise” 45 centimeters, so again become a safe and open to all visitors.
