when did the leaning tower of pisa open
Leaning Tower of Pisa
The tower was closed to the public on January 7 , 1990 , after more than two decades of stabilisation studies and spurred by the abrupt collapse of the Civic Tower of Pavia in 1989 . The bells were removed to relieve some weight , and cables were cinched around the third level and anchored several hundred meters away . Apartments and houses in the path of the tower were vacated for safety . The solution chosen to prevent the collapse of the tower was to slightly straighten it to a safer angle by removing 38 cubic metres ( 1,342 cubic feet ) of soil from underneath the raised end . The tower was straightened by 45 centimetres ( 17.7 inches ) , returning to its 1838 position . After a decade of corrective reconstruction and stabilization efforts , the tower was reopened to the public on December 15 , 2001 and was declared stable for at least another 300 years . In total , 70 metric tons ( 77 short tons ) of earth were removed .
