View of Rome in a tower is just a historical memory which gives us some idea with insufficient subjective images (paintings of medieval period ).

The towers was subjected to earthquakes, like what happened to the two major towers (which is Milizie tower and Conti tower), in which there was the need for destruction or demolition (like the mass structure demolition by Brancaleone of Andalò in 1252); at the end there was the need to adapt to the towers that survived to transform it in a view deck, this started in five hundred.
