colonnade (kŏlənādˈ), a row of columns usually supporting a roof. Colonnades were popular with the Greeks and Romans, who employed them in the stoa and the portico; they have continued to be used throughout the Middle Ages, the Renaissance, and modern times. See column.
a row or rows of columns supporting a horizontal roof structure. Outdoor colonnades, which are either porticoes or galleries, are usually attached to a building to unify its isolated elements (for example, the Palladian villas). A colonnade also visually relates a building to its courtyard or square (for example, the colonnade of the Kazan Cathedral, Leningrad, 1801–11, architect A. N. Voronikhin) and its natural setting. Some colonnades are independent structures, such as the Colonnade of Apollo in Pavlovsk (1780–83, architect C. Cameron). Interior colonnades usually surround large halls, serving both to divide and unite various parts of a grand interior (for example, the colonnade in the former Catherine Hall in the Tauride Palace, Leningrad, 1783–89, architect I. E. Starov).
