No one knows if the famous bell tower of Pisa will fall or not, but there is one clear thing: every year it tilts two millimeters more. At present its inclination has already a critical value of 2.3 meters and the Italian government has adopted some measure to save the bell tower. For security reasons, almost twenty months ago tourists were forbidden to climb the area, but they also want to place ten steel hoops. This measure will be temporary until the elaboration of a more complete plan.

Ten steel cables of one centimeter in diameter will compress the tower between the first and the last tabs. We are also studying the hydraulic support that isolates from the variations of the water table at 40 meters depth. With the ten rings you will be offered a little security for four years.
