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).
