Another one of many interesting Leaning Tower of Pisa facts is that the structure is not just leaning but is also curved. As the tower started to lean, the engineers tried to minimize the height difference between either side of the tower to lessen the tilt. They tried to fix the lean-on floors that were built later on by increasing the height of the floors on one side that appeared shorter. This resulted in the tower being slightly curved.

The city of Pisa is known for its marshy land, and the city is named Pisa which is Greek for marshy land. Since there are other buildings built on the same land as that of the bell tower, there are other leaning towers in the city. The land soil has caused other structures to sink and lean just like the Leaning Tower of Pisa. The other leaning towers are the bell tower of the Church of San Nicola and the bell tower of St. Michele Dei Scalzi.

Even though its eccentricity is what sets the bell tower apart, the tower ended up leaning due to poor design and planning. The engineer of the Leaning Tower of Pisa had insufficient knowledge of soil mechanics which resulted in the unavoidable flaw. The marshy land of Pisa is composed mainly of clay and sand. As the structure started to sink and lean, the construction had to be paused and re-imagined.

As strange as it may sound, amongst all the Leaning Tower of Pisa facts, this fact takes the cake. There was a time during the construction of the third floor when the tower started to lean northward as opposed to its original southward lean. It is suggested that the change of direction happened as the gravity was thrown off. Although, after building the fourth floor and onwards, it returned to its original tilting position.

As the land soil remained the same, the bell tower continued to sink in and the lean kept progressing. Engineers and architects put a lot of time and effort to curb the situation by solidifying the foundation to stop it from sinking and leaning further. The bell tower had a maximum of 5.5 degrees tilt by 1990 until the foundation was further solidified and put an end to the tilt.

The Leaning Tower of Pisa, situated in Italy, could potentially resume tilting due to the ongoing geological factors. Its foundation rests on unstable soil composed of clay, silt, and water, which could cause the tower's angle to change over time. Engineering interventions, including soil removal and counterweights, have successfully stabilized the tower's lean, but the risk of future movement remains. Continuous monitoring and maintenance are essential to ensure its preservation.

The Italian dictator Benito Mussolini detested the bell tower of Pisa. He considered it a national disgrace and was ashamed of the structure. In an attempt to fix the tilt, Mussolini ordered to drill holes into the base of the tower and fill it with grout to strengthen its foundation. However, the efforts went in vain as it caused the tower to lean further.

Standing tall at 57 meters of height, the Pisa tower also served as a military base during World War II. The German army used it to survey the surrounding areas from the top of the tower. It was used as a prime lookout spot by the soldiers to keep an eye on the enemy.
