| 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. |
