Pisa Leaning Tower - Strange architecture of the world

If you think that people deliberately build the Tower of Pisa to attract attention, it is unfair for Pisa. Pisa has also stood upright, but the land that Pisa is 'reigning ' is getting subsided, so Pisa is increasingly inclined and at risk of collapsing in the future.

Yet it was this unintentional inclination that made Pisa famous all over the world and made the tiny city of Pisa in Italy's Tuscany region - where the Tower of Pisa is located - richer thanks to the massive number of tourists rushing. come here. Among them, there is the writer Mark Twain, who gave the tower of Pisa a love affection when calling it the strange architecture of the world. No one at the time when the tower was rebuilt could be expected that the Pisa tower would become a world wonder and be recognized as a cultural heritage by UNESCO.

The Pisa Tower began construction on August 9, 1173.

The Pisa Tower began construction on August 9, 1173. 5 years later, when built to the 3rd floor, Pisa tower started to tilt. There are many reasons for this long construction, mainly because the city of Pisa conflicts with neighboring Florence, along with the difficulties of building towers on land subsidence.

Many measures were taken to keep this 14,500-ton block standing on unstable ground such as: using trapezoidal stones, creating curvature for the tower, building one side higher than the other . Pisa during the time. It met many rumors like it would be dangerous, the leaning tower was useless . Beyond it all, Pisa still stood there, 55.86m high with 8 floors and 294 steps from the ground to the top. The Pisa Tower is now recorded as tilting 5.5 degrees. Visitors to the visit tower must go to small groups to avoid causing damage to the Pisa leaning tower.

At the Miracle Square (Piazza dei Miracoli), if you pay close attention you will see not only the leaning tower of Pisa but also the surrounding structures such as churches and chapels are not straight. Only their horizontally bulges should be tilted a bit and not significant, while the Pisa tower tilts and stands out because of its tall, slim figure.

Pisa's leaning tower is also known as the place where Galileo scientist experimented for his theory of mass. Galileo was a resident of Pisa in the 16th century, he climbed the Pisa tower and dropped two balls of different weight from the top of the tower. Since then, the theory that we have learned in physics has been born: the weight of the object does not affect the acceleration of the object, meaning that heavy or light objects fall at the same speed . (1971: David R Scott confirmed this when he released bird feathers and a hammer in a vacuum at the moon and they touched the ground at the same time).

The Tower of Pisa tilted one millimeter more every year.

Pisa resiliently survived the bombing of World War II when the Nazis took Pisa as an observatory and shelter. In the years of the 90s, Pisa tower tilted one millimeter each year, causing the city of Pisa to slash 30 million euros to repair, including relocating 70 tons of land in place and replacing with cement with lead to increase stamina for the tower.

It is more likely that Pisa each year will be more inclined until the collapse in about 300 years.

According to the curator of the Leaning Tower of Pisa, engineer Michele Jamiolkowski, it is likely that Pisa will tilt each year more until it collapses in the next 300 years. The life span of more than 600 years, Pisa leaning tower is a convincing example demonstrating the appeal of the slant line that you can still be famous and successful with your own uniqueness, even if you may not be a person. the most beautiful. The Pisa Tower was built and existed on Magic Square. Well, hopefully the magic will keep Pisa from falling someday.
