When in front of a building, screening the door (Latin porta), it is called a portico, when enclosing an open court, a peristyle. A portico may be more than one rank of columns deep, as at the Pantheon in Rome or the stoae of Ancient Greece. Paired or multiple pairs of columns are normally employed in a colonnade, but the porch of columns that surrounds a peripteral classical temple (such as the Lincoln Memorial in Washington, D.C.) can be termed a colonnade.
At the British Museum, porticos are continued along the front as a colonnade. In U.S. sports stadiums, there are several famous examples of colonnades, including: Harvard Stadium in Boston, whose entire horseshoe-shaped stadium is topped by one, the two twin sets on either side of Soldier Field in Chicago (although these are no longer visible from inside the stadium as of the 2004 renovations), and Memorial Stadium at the University of Illinois, which are located on the façade of the grandstands on either side of the field, and the University of Virginia's former American Football stadium Lambeth Field has colonnades that wrap around the top of the bleachers. According to Emporis, the New York State Education Building in Albany, New York, has the longest colonnade in the United States, with 36 Corinthian columns.
