Sightseeing in Tuscany picture - The problem of the inclination of the Tower is the aspect which, over the centuries, has most fascinated and aroused the curiosity of visitors, art enthusiasts and scholars, rendering the building world famous. This is also due to the fact that, to this day, the reasons behind the inclination of the Tower are in many ways mysteries. Experts have debated at length, in particular in the XIX century, over whether or not the inclination came about as a result of problems of statics which emerged during the construction of the Tower: in other words, whether the inclination was the result of an unforeseen and inevitable progressive subsidence of the ground, or whether it constituted an effect consciously desired by the architect.
