Architecture:

The Leaning Tower of Pisa is undoubtedly an important building in the history of architecture. Its bold circular architectural design had already shown its originality to the world before the severe tilt occurred.

While it is not uncommon to find Italian bell towers of an earlier date with circular foundations - similar examples can be found in Ravenna, Tuscany and Umbria - the Bell Tower of Pisa is considered to be independent of these archetypes, and to a much greater extent it was designed independently of its predecessors, drawing on their experience of architecture, and developing its circular architecture in a uniquely Pisan style.
