Italy Architecture

Italy has an extensive and diverse architectural style, which cannot be classified by period or region due to Italy’s division into numerous small states before its unification in 1861.

Influenced by Greek and Etruscan architecture, Roman architecture assumed its own characteristics.

The Romanesque movement, one of Italian architecture’s most fruitful and creative periods, spanned from approximately 800 AD to 1100 AD. The style was called “Roman”-esque because of its use of Roman arches, stained glass windows, and curved columns, commonly featured in cloisters.

The Gothic architecture appeared in Italy in the 12th century. Italian Gothic always maintained a peculiar characteristic that differentiated it from its French counterpart. In particular, the bold architectural solutions and technical innovations used in France never appeared in Italy. Instead, Italian architects preferred to keep with traditions established in the previous centuries.

Italy of the 15th century, particularly Florence, was home to the Renaissance. The new architectural style of the period did not slowly evolve in the same way Gothic grew out of Romanesque but was consciously brought into being by prominent architects.

Italian Baroque (or Barocco) is a stylistic period in Italian architecture that spanned from the late 16th century to the early 18th century.

The Neoclassical movement influenced Italian architecture in the late 18th and early 19th centuries. 

The UNESCO list of World Heritage Sites currently includes 54 sites in Italy. Additionally, there are 32 more sites on the country’s tentative list.
