What do you think?
U nlike many great buildings of the time, the Tower of Pisa does not serve a practical purpose. Rather, it was constructed as a boastful statement to Pisa's nemesis, Florence. At the time, the two were the modern equivalent of today's "superpowers" and ruled much of the world through their control of the sea. The two were also bitter rivals, fighting for supremacy. In fact, construction of the tower was interrupted because of wars in 1178 with Florence, 1185 with Florence again, and in 1284 with Genoa, It was during one of these breaks in construction that the tower's infamous tilt was discovered. It was only three stories tall at the time, but rather than abandon the project, construction continued until the tower reached its full height of 58.36 meters when measured from its foundation, or just 55 meters when measured from the ground. It was at this early stage, too, that the tower first served its intended purpose -- the ringing of bells. Documents have survived that show that a bell was first placed at the top in 1198. When construction continued, it was replaced by seven bells at the top in 1350. There are two theories about why the tower leans.

The most popular reason is because of the unstable soil beneath. Its of 14,700 metric tons of grey San Giuliano limestone is simply too much weight for the ground to hold. The local soil is mostly marshy clay and the tower exerts a force of 497 kPa on it. But some historians don't think the lean was an accident. They believe it is an intentional architectural design that produced the tilt. However, recent measurements and analysis of the soil have put this school of thought in doubt. Over the centuries there have been a number of attempts to straighten out the tower. One try in 1934, concrete was pumped underneath the tower. Another in 1838 involved excavating the earth and drying out the ground the tower rests on.. Recently, a pair of suspenders were attached to lead weights and slung over the tower which helped a bit. Architecturally, the building is summed up thusly by its official web site:<br><br>
"The six arcades, the base on which they are placed and the belfry above them subdivide the Tower into eight segments, known as orders. The interior order is animated by a band of blind arches placed on half columns. Underneath the arches are lozenged rhomboid decorations inlaid with coloured marbles, each containing a rosette in relief at the centre. The wall facing is interrupted by narrow round-arched lancet windows and, to the west, by the only door of accessa rectangular opening framed by an architrave. Above the architrave a falcate arch with a carved archivolt rests upon two capitals in continuation of the piers, forming an aedicule containing a fourteenth-century bust of the Madonna and Child. At the sides of the portal there are friezes with decorations showing animals and imaginary beasts. These, alongside a singular representation of ships (the Pisan port?), accompany the epigraph which commemorates the foundation of the building. The cylindrical belfry which concludes the building, of a smaller diameter than the floors below, bears an external decoration composed of closed and pierced lunettes, which rest alternately on pedestals and columns, whereby under every pedestal (bearing two closed lunnettes) there is a door, while the single pierced lunnettes supported on columns are lengthened to form windows. The belfry is reached via a narrow spiral stair, and in turn allows access to the summit of the tower by way of a stair cut into the wall."

  • The height of the tower varies over time, though it is usually around 183 feet tall.
  • The architect of the tower is unknown. However, it is believed that Bonanno Pisano and Guglielmo of Innsbruck, Austria may have designed it, or possibly Diotisalvi.
  • Precise location: 43°43'0" N x 10°22'60" E.
  • Construction began August 9, 1173.
  • There is an inscription at the entrance which reads "A.D. MCLXXIV. CAMPANILE HOC FUIT FUNDATUM MENSE AUGUSTI" (In the month of August, A.D. 1174, this bell tower was founded.)
  • It is said that Berta of Bernardo was the impetus behind the tower. Legend has it that when she died on 5 January, 1172 in her will she left 60 coins to pay for the first building blocks of the tower.
  • There are 293 steps to the sixth arcade.
  • August, 1173: Construction begins.

  • August, 1173: Construction begins.
  • 1998: The tower's lean is measured at 13 feet:- considered a dangerous pitch. Excavation work begins to correct some of the tilt.
  • May, 2001: Engineers have begun removing two pairs of steel suspenders intended to take some of the lean out of the Leaning Tower of Pisa. The cables were attached in 1998 just in case something bad happened during excavation work undernearth the tower. The digging is intended to adjust the tilt of the Leaning Tower which had to be closed to the public because it was becoming dangerous.
  • January, 2001: The Tower now leans 11 feet, eight inches.
  • June, 2001: Engineers have finished tinkering with the Leaning Tower of Pisa. After years of work they managed to straighten it enough to make it safe for tourists.
  • December 15, 2001: A month late, the tower re-opens to tourists.

I think everyone who is capable should climb the leaning tower at least once, you'll never know if you'll be able to again! They constantly monitor the steadfastness of the structure and won't let you up if it's not safe. I suggest making arrangements and scheduling your tickets ahead of time because they only let you up in shifts of about 20 min each and you can only go up with about 10 or so other people. If you just show up and try to get tickets, you could end up waiting a really long time. Also, don't go to the tower to buy tickets, go to the area where you check your purses (you can't bring them up with you) and buy your tickets there.

this is an amazing building...a historical icon that used to be a part of galileos exxperimants...the tilt is one of a kind and is the purpose of the tourists to visit...hope they will not attempt to make it stand as the other buildings do as long as the safety of the people in its vicinity is concerned...

Id say that the building should stay the way it is for the people in the near future would all want to see it for themselves, i mean people its going to be apart of history so it should be kept alive and ad it is now, without being straightened out, i cant wait to visit the place :)

this buildin is magnifcent and very amazing that its still standing even though it weighs so much and causes pressure in the soil grounds which is why it leans and it was one of the only buildings that werent bombed down in pisa through world warII furthermore it is the bell tower of a beautiful cathedral and if it wasnt leaning this tower wouldnt be a landmark cuz thats what makes it special

It's ugly, badly designed (the upper floors were added with an opposite tilt in order to balance) and misengineered. It's not even that great sight. I'm not sure why so many people go to see it.

The inclination of the leaning tower of pisa was measured to roughly 5.5 degrees in the early 90s. Extensive investigations and computer modelling revealed that if action was not taken then masonry on the second storey would fail and the tower would be lost forever. The commision in charge of the tower decided to extract soil from below the towers north side in order to allow the tower right itself. The target amount was a mere 0.5 degrees, invisiable to the naked eye but enough to relieve stresses and prevent the tower from falling. By 2002 this reduction was achieved and the tower is now stable so that it can be enjoyed by all for years to come.

people argue the fact that the leaning tower should or should not be straightend but i think that it should because yes its history and if we still want to see it and the next generation of kids then at least anchor it so that we will have that chance as well as our kids.

This is an amazing building that people are trying to restore so that many people in the future can enjoy it. They aren't trying to staighten it completly, they are just making it safe enough to keep it standing and so people can still visit it in the future, we don't want tosee it fall, it's just to beautiful, nor do we want it rebuilt because it is a piece of history that should be kept

May 27th, 2003
I think the tower should be brought down and rebuilt to how it was meant to be built.

I Just got back from Europe And it was such an exciting adventure. I was so glad that I got to explore Italy and the town of Pisa. The Leaning tower was such a fantastic sight to see. And it was so Exhilerating climbing all those stairs. I am so glad that that tower did get fixed so it didnt fall over, also because they didnt do it all the way straight.

March 21st, 2003
In 1838, the architect Alessandro Della Gherardesca dug a walkway called the catino around the base of the tower to expose the buried foundation steps and column plinths. Because the catino was below the water tablenon the south side, the excavation triggered an inrush of water, with a subsequent half-degree increase in the lean. He acctually made it worst. This was probably because of the lack of knowledge of Geoengineering then. However the straightening had to be done, it was gonna cause a catastrophy! anyways, 10inches is not obvious :) doesnt make a difference on the naked eye!

January 11th, 2003
They had to fix the lean! Do you want the building to just topple over alltogether? Then how could anyone enjoy it?

January 5th, 2003
Straighting the tower is ruining history. The lean has a story and is a major part of it's history-and it's name!

December 4th, 2002
I went before they straightened it and climbing those tilted stairs was such an exhilerating experience! Still, if it was dangerous, it was worth it to straighten it a bit so that others can also enjoy that spiraling walking-on-the-ceiling sensation.
