Colonnade:
In classical architecture, a colonnade is a long sequence of columns joined by their entablature, often free-standing, or part of a building.[1] Paired or multiple pairs of columns are normally employed in a colonnade which can be straight or curved. The space enclosed may be covered or open. In St. Peter’s Square in Rome, Bernini’s great colonnade encloses a vast open elliptical space. [Wikipedia]
Noted on a sign in the movie The Hustler (1961).
