My name is Aoife, and my project is on the Leaning Tower of Pisa.
As you read through it I hope you will learn some interesting facts about this unusual tower and also some information about its history.
Anyway, I hope you enjoy it.

 

Leaning Tower of Pisa

HOW I MADE MY MODEL

First I got a long tube and I a couple of layers of paper mache on it. Then I rolled up eight sheets of newspaper and glued them on to make eight storeys and I painted it black. Then I cut out the shape of the columns for each storey from some grey rubber type material and I glued on matches to make the columns. I used a small carton to make the belfry and I drew the windows and seven bells on it. I used a match and some red material to make the flag. I drew a map of Italy on a piece of stiff card for the base, and I put the tower on it. I propped the tower on one side to make it lean.

HISTORY OF THE TOWER

The Leaning Tower of Pisa is built in the town of Pisa in Italy.
It is a bell tower seven stories high with a belfry on top.
The architect of the tower was Bonanno Pisano, a well known resident of Pisa.
The building was started on 9th August, 1173 and was finished around 1350.
When the construction reached about one and a half meters up on the third floor, because of marshy and unstable soil, the tower was found to be leaning so the work was stopped.

The restarting of the work took place in two phases, during which they tried to reduce the slope.
The second phase of the 13th century started, probably, about the year 1272 to 1275. At the 7th storey some round arch windows for the bells were made.
The belfry was constructed by Tommaso son of Andrea Pisano around 1350.
In 1934 cement was injected into the base and this has been blamed for speeding up the lean.
The tower was closed to the public in 1990. In 1995, 600 tons of lead were added to the north side and a tilt of 2.5mm was recorded overnight in September 1995. A further 230 tons of lead were added after the overnight tilt. Correction from 1990 to 1999 was 25mm and amount of tilt correction from 1999 to 2001 was 43.8cm. The tower was reopened to the public on December 2001.

THE BELFRY

The completed belfry replaced the temporary one on the seventh level, where places for the bells are still evident. There are seven bells. The biggest one is made out of gold and is called dell’Assunzione or l’Assunta (Our Lady of the Assumption)
It weighs 7,600 lbs and was cast in 1655. The next one is called del Crucifisso (of the Crucifix). It weighs 5,168 lbs and was cast in 1572 and again in 1702
La Pasquareccia (the Easter Bell) is the oldest bell. It was cast in 1262 and weighs 2,204 lbsThe fifth bell is called Del Pozzetto, it weighs 1,434 lbs and was cast in 1606 San Ranieri, a bell from 1735 dedicated to Saint Ranieri, patron saint of Pisa. It weighs 3,186 lbs. Vespruccio cast in the fourteenth century and again in 1501 weighs 2,200 lbs and is rung in the evening (vespers). La Terza (third) because it was rung at the third hour, that is at nine in the morning. It was cast in 1473 and weighs 660 lbs.

 

THE STAIRS

The stairs of the tower are made of marble, as are the walls and the 200 columns of the tower. There are 293 steps which start on the ground floor and reach to the seventh balcony. The large square where the bell tower stands was used once a year to host a Mediterranean exhibition fair where merchants from all regions showed their goods. The bell tower was an ideal place from which the fair could be seen, and as there were some very important guests, the stairs reaching the tower had to be well built.
