### Instruction:
Is Leaning Tower of Pisa structure stabilized?

### Input:
The tower was closed to the public on 7 January 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 a potential fall of the tower were vacated for safety. The selected method for preventing the collapse of the tower was to slightly reduce its tilt to a safer angle by removing 38 cubic metres (1,342 cubic feet) of soil from underneath the raised end. The tower's tilt was reduced by 45 centimetres (17+1⁄2 inches), returning to its 1838 position. After a decade of corrective reconstruction and stabilization efforts, the tower was reopened to the public on 15 December 2001, and was declared stable for at least another 300 years. In total, 70 metric tons (77 short tons) of soil were removed.
