Portico

The amphitheatre hath two portici as that at Niſmes.

The great house itself was a large, white, wooden building, with wings on three sides of it. In front, a large portico, extending the entire length of the building, and supported by a long range of columns, gave to the whole establishment an air of solemn grandeur.

The long-closed G.W.R. station alongside has a decidedly derelict-looking frontage, with eight gargoyles or figureheads still clinging to the portico.

[…] Porticus Milliaria (portico of the thousand paces) which was the longest, if not the most attractive, of the many portici of ancient Rome.

The portici enhance street life today, as they did when they were first constructed, not simply by providing protection from sun and rain, but by providing attractive public spaces for friends to meet, for business people to conduct business, for vendors to display their wares, for musicians to play their music and for beggars to beg. […] Most tours of Bologna begin in the Piazza Maggiore, on the site of the Roman forum, but it’s important to remember that the piazza didn’t begin to take its present shape till toward the end of the 13th century—after the age of medieval towers, after the citizens began to enjoy their portici.

These lines are possibly meant to represent two portici flanking the building on its long sides.
