The Tower of Pisa in 3D

The Spanish newspaper La Vanguardia has published a really interesting article which explains how the Leaning Tower of Pisa has been stabilized and protected from further subsidence and collapse. This interesting article has been made even more gripping by being illustrated with some fantastic 3D modeling of the Tower and its environs.

This is How the Tower of Pisa was Prevented from Falling explains how the Tower of Pisa was constructed in the 12th Century and how the tower began to lean during its early construction.Even during the construction of the first four floors the tower began to lean towards the north.During the construction of the higher floors measures were taken to try to keep the tower's central axis vertical. Then, ever since the tower was completed, numerous efforts have been made to prevent further inclination. 

Using a 3D model of the Leaning Tower of Pisa La Vanguardia illustrates the engineering behind some of the attempts that have been made to halt the Tower from leaning even further to the north. In particular the newspaper explains some of the measures undertaken during the closure of the Tower of Pisa, between 1990 and 2008. These stabilization efforts are said to have made the tower safe for at least another 200 years.
