This free standing Campanile, or bell tower, of the Cathedral St. Mary Pisa, is located in Campo de Miracoli (Field of Miracles) in Pisa Italy. Construction of the tower began on August 9, 1173 and was not completed until 1372. During this time there were several stops in construction, most notbaly those due to wars with Firenze in 1178 and 1185 and also the War with Genoa in 1284.The original architect of the tower was Bonanno Pisano. Unfortunately, after only five years into construction, just after the third floor was completed, the tower began to tilt downward leaning to the southeast. The reason is that the tower has a stone base which is only about 10 feet thick. This base rests on soft sand, rubble and clay which were not sufficient to keep the 16,000 ton tower vertical as it settled.One hundred years after Bonanno Pisano began construction, architect Giovanni di Simone continued construction of the tower, completing the 7th floor in 1319. In an effort to compensate for the tilt, builders made each new tier a little taller on the short side but the weight of the additional stone cased the tower to lean in the other direction. The structure was officially completed with the addition of the bell tower built by Tommaso di Andrea Pisan in 1372. The Leaning Tower of Pisa stands at a height of approximately 185 feel. There are 2196 or 294 steps; the 7th floor has 2 fewer steps on the north facing staircase. Prior to the restoration work performed from 1990 to 2001 the tower leaned at an angle of 5.5 degrees. The current angle is approximately 3.99 degrees. This means that the top of the tower is 2ft 10 in from where it would stand if the tower were perfectly vertical. The tower contains 7 Bells, one for each note of the musical major scale.
