In
classical architecture, a 'colonnade' denotes a long sequence of
columns joined by their
entablature, often free-standing, as in the famous elliptically curving colonnades that
Bernini added to the facade of
Saint Peter's Basilica in
Rome, which embrace and define the
Piazza. Compare the sequence of baluster forms that go to make a
balustrade.
A colonnade of single columns is often termed a ''screen.'' 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) can be termed a colonnade. Since the largest number of columns across the front of a classical temple front is normally eight (constituting an ''octastyle'' temple), it might be argued that a colonnade must have more than eight pairs. Certainly the proportions of a colonnade require that it be more than twice as long as it is tall.
At the
British Museum porticos are continued along the front as a colonnade. In American sports, 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.
