Roman temples, rarely peripteral (surrounded by columns), had a portico at the front end only.

Porticoes were widespread in antiquity and were part of the architecture of ancient Greek temples; during that epoch freestanding porticoes were also often constructed. The portico was also important in modern European architecture, particularly during the classical period of the 18th and the first third of the 19th century. In 19th- and 20th-century architecture, pillars have often substituted for columns in portico construction.
