The Leaning Tower of Pisa Just Got a Little Bit Straighter

Pisa's famous bell tower has just lost a little bit of its lean, according to a new report by researchers. The Italian tower, which has been tilting perilously for more than 800 years, has straightened by 2.5cm (1 inch) since 2001 thanks to a massive restoration project.

The Tower of Pisa has been leaning to one side pretty much from the beginning-the tower took nearly two centuries to build and it was obvious from the start that things were a little off kilter.

By the early 1990s, the tower was leaning nearly 18 feet, and each year, the tower was tilting more and more, with the incline increasing by more than a millimeter (0.04 inches) a year. That might not sound like much, but experts feared the building could collapse all together.
It has taken engineers years to stabilize the tower, which included digging tunnels under one side of the structure to give its foundation room to shift, and attaching steel cables to the tower to keep it upright. It worked, and the tower has been straightening as predicted. In fact, engineers say that theoretically, they could straighten the tower completely. That, however, is unlikely to happen. More than 6 million people visit Pisa each year lured by the sight of the leaning tower, so while locals are happy to see the building restored, they're not eager to see it straightened anytime soon.
