Portico

A portico is a porch leading to the entrance of a building, or extended as a colonnaded or arcaded walkway. Its roof is supported by columns or pillars, and is typically open or partially enclosed. Porticos are frequently found in classical architecture and architecture inspired by classical styles.

Typically, a portico features a pediment, a triangular space forming the gable of a two-pitched roof above the horizontal structure of the portico. The design of the portico often reflects the architectural style of the main building. The columns used can be of various classical orders, such as Doric, Ionic, or Corinthian, each characterized by distinct features and proportions.

While providing shelter from the elements, the portico also serves as a decorative architectural element, adding visual interest and grandeur to a building's facade. Historically, porticos were common in ancient Greek temples and Roman public buildings, and their use has continued through various architectural movements, including Renaissance, Neoclassical, and Beaux-Arts architecture. Today, they can be found on a wide range of buildings, including residential homes, public institutions, and commercial structures.
