Leaning Tower of Pisa

ROME (SINDO) - The leaning towers of Pisa in Rome, Italy, was declared safe to visit the turis.Menara who became one of the wonders of the world that has been declared stable for the next 300 years.

Stability of the tower of Pisa is the first time in 800 years the tower was stopped moving. "Prediction of us have been realized and the tower can rest at least until 300 years from now," said the Italian engineers and geologists Professor Michele Jamiolkowski yesterday. The tower is currently located in the slope of the original position, after a few scientists managed to justify his position.

The tower is predicted to have excess slope of up to 40 cm.Correction tower project lasted from 1991 to 2001. Slope monitoring project was to cost $ 40 million (worth Rp372, 5 billion). The team had been working for about 12 years to stop the tilt of the tower. The researchers examined the degree of excess levels of the slope that occurred at the Tower of Pisa.

To fix the position of the slope, scientists could take back the building in perlahan.Mereka also inject liquid cement into the ground to strengthen the base of the tower so that the slope is located in the same position since the tower was built.

In 1990, the leaning tower was closed for public consumption because of its slope progressively from year to year. Tower of Pisa is the bell tower of the cathedral. Actually, the tower was made to stand vertically like a tower bell in general.

However, began to list shortly after its construction began in August 1173. Height of this tower is 55.86 meters from the lowest ground level and 56.70 m from the ground surface beneath the wall tertinggi.Kelebaran reached the peak of 4.09 meters and 2.48 meter.Bobotnya estimated at 14 500 tonnes. Tower of Pisa has 294 stairs.
