The Leaning Tower of Pisa is continuing its steady return to "straightness",according to reports.According to a group in charge of monitoring the structure,the tower has recovered roughly 2.5 cm of its vertical incline between 2001 and 2013.Since 1992,the vertical inclination of the tower has moved from 4.5 meters to 4.1. Several "rescue" interventions,some of which are underground,were conducted to stabilize the tower and the researchers were able to achieve a 2.5 cm 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.
