Cathedral Group at Pisa 

 This group of buildings, built from 1053 to 1272 at Pisa, in Italy, includes a campanile (bell tower), 
 better known as the Leaning Tower, rear right; a cathedral, center; and a baptistery, left. The tiers 
 of open colonnades (series of columns) throughout the group are characteristic of the Romanesque style 
 of architecture, which preceded the Gothic style in western Europe. The campanile began leaning during 
 construction due to the settling of the foundation.
