 Leaning Tower in Bologna closed due to concerns that it could fall

A medieval tower in Bologna, Italy, that tilts as much as its well-known twin in Pisa, has been shut off out of concern that it would fall.

In order to confine debris in the event of a collapse, authorities have started constructing a 5-meter (16-foot) high barrier around the 12-century Garisenda Tower.

The four-degree tilt of the 47-meter (154-foot) tower has been monitored, and variations in the tilt's direction have been noted.

The situation was described as "extremely serious" by the municipal council.

One of the two skyscrapers that dominate Bologna's skyline is the Garisenda Tower. The second, the Asinelli Tower, is about twice as tall, has a little inclination as well, but not as much, and is often accessible for visitors to climb.

The buildings were constructed between 1109 and 1119, yet the Garisenda's height was lowered in the fourteenth century since it was already slanting. Dante's 1321 completion of The Divine Comedy includes a reference to the structure.

After examinations found degradation in the materials comprising Garisenda's base and sensors detected changes in the structure's tilt, the site was first closed in October.

In order to protect the tower, the council has initiated a civil defense strategy, stating that this activity "represents the first step in making it safe".

It added that in addition to keeping debris contained, the barrier would shield individuals and structures nearby in the case of a collapse. It further said that the tower will have metal rockfall netting put there.

While the tower and the plaza below it are anticipated to stay closed for many years while repair work is done, the barrier's construction will be finished early in the following year.

The city has started a crowdfunder to help with the repair costs, as they anticipate that the barrier alone would cost €4.3 million (£3.7 million).

"A commitment from the whole municipality and from people around the world who love Bologna and all of its most important symbols" would be necessary, the project was described as a "extraordinary challenge" by the publication.
