Recent reports say that the Leaning Tower of Pisa is continuing its steady return to "straightness".
An annual report released by the official surveillance group in charge of monitoring the famously tilting structure has revealed that the tower has recovered roughly 2.5 centimeters (almost one inch) of its vertical incline between 2001 and 2013, the Huffington Post reported.
AdvertisementSince 1992, the vertical inclination of the tower has moved from 4.5 meters to 4.1.
Several "rescue" interventions- some of which were underground- were conducted to stabilize the tower and the researchers were able to achieve a 2.5-centimeter decrease over the last decade.
The slight progress has allowed the tower to retain its popular modifier and experts say that it can now be considered safe for the next two to three centuries.
