How is it possible? – The Leaning Tower of Pisa
Surely everybody has been wondering about how possible that the Leaning Tower of Pisa is inclined.
Let’s decode its secret!
Pisa is one of the oldest cities in Italy. It has an extremely long history.
Pisa was conquered in the 2nd century BC by Romans. It had been prospering for a long time, before it started to decline in the lately 11th century.
But after having some difficulties in the Middle ages, this town got bigger and bigger. Not just its population, but also its tourism has been rising since then.
The construction of the Leaning Tower of Pisa took for more than 200 years. It is situated behind Pisa’s cathedral and is the third oldest structure in the city’s Cathedral Square, after the cathedral and the Pisa Baptistry.
Work on the ground floor of the white marble campanile began on the 14th of august in 1173, during a period of military success and prosperity. This ground floor is a blind arcade articulated by engaged columns with classical Corinthian capitals.The tower’s tilt began during construction, caused by an inadequate foundation on ground too soft on one side to properly support the structure’s weight.
What’s up with its sizes?
The tower has 295 steps; the seventh floor has two fewer steps on the north-facing staircase. Prior to restoration work performed between 1990 and 2001, the tower leaned at an angle of 5.5 degrees, but the tower now leans at about 3.99 degrees. This means the top of the tower is displaced horizontally 3.9 meters from the center.
It’s 56 meters high, so the people around it seem to be so small. The outside diameter of the Leaning Tower of Pisa’s base is 15.484 meters. The weight of tower is approximately 14,500 tonnes.
