This condition suggested the crossing of position of a series of architectural masks or the triple hall in the center by a great transept, screens, as we have already explained.

This area they occupied with external and internal galleries of two stories. These galleries naturally develop pavilions 50 feet square
where they intersect at the corners, and they are interrupted, in the center of the two principal façades, by main-entrance pavilions; that on the north facing the Administration Building, and that on the east facing the corresponding side porch of the Agricultural Building. It has already been noted that the architects of the court considered that it was necessary to establish sheltered ambulatories along their fronts. In accordance with this agreement, the long intermediate stretches of façade or curtain-walls of this building, between the pavilions, are faced with porticos; but in this case the porticos are arranged in two stories to correspond with the interior, treated somewhat after the manner of Claude Perrault in the east front of the Louvre, each division having Corinthian colonnades of 23 columns 2772 feet high on the long
façades, and of 9 columns on the end façades, the spacing of these columns being multiples of the structural divisions of the great interior bays. Unlike the famous Paris example, however, the basement upon which these colonnades are placed is pierced with an open arcade to form the lower ambulatory, the ceiling of the latter being treated with a dome in each bay, and that of the former with richly embellished panels. To relieve the scrupulously scholastic accuracy of the main order, and to recall the days of Columbus and of Ferdinand and Isabella, the apertures in the rear walls of the upper porticos are treated with the picturesque freedom of the Spanish Renaissance, and the arms of Spain and the portrait of Columbus are frequently repeated about them.
It became evident to the architects, in the evolution of their design, that the light and open character of these long twostoried porticos needed some strongly contrasting form of relief and support, to be obtained by transition to an expression of solidity and massiveness in the corner and middle pavilions. For this reason they were led to treat the latter very boldly as plain wall-surfaces abruptly interrupting all the horizontal lines of the orders of the curtain-walls, and carried 35 feet higher, there finishing with a level cornice. On each front this plain wall-surface they divided in three pavions, of which the outer, 29 feet wide, are treated as towers, the wider intermediate part being slightly recessed between them. Upon these towers, which contain staircases, they placed open octagonal lanterns, in three diminishing stories, rising to the height of 102 feet, like spires enriched with balustrades and finials, somewhat Romantic in character, and following suggestions contained in Spanish or Mexican examples. On the north pavilion toward the court, and opposite the south entrance of the Administration Building, the architects embedded in this central division a temple-like portico 75 feet wide and 90 feet deep, the portion developed outside the pavilion, and forming the exterior, being apsidal or semicircular in plan. This portico they treated with a colossal Corinthian order 60 feet high, crowning the apsidal projection with a low half-dome behind a balustrade, with a pedestal and statue over each column somewhat like the
famous circular porch of the calidarium in the seen, in parts by motives suggested by the highly Baths of Caracalla. The east portico practically ornate Renaissance of Spain.
