Immediately upon entering the terrace one encounters marble candelabra, where low-relief panels depict Justice holding her sword and scales and the Three Fates weaving the thread of life. The bronze bases of the flagpoles there, designed by Gilbert and modeled by John Donnelly, Jr., are decorated with numerous symbols of justice (scales and swords, books, masks and torches, pens and maces) as well as the four elements (earth, air, fire, and water). At the closure of the terrace a full-story staircase draws one upward onto the dipteral octastyle portico.
Throughout this entire processional route, one is surrounded by white Vermont marble with an unusually high mica content. Reflections are so brilliant on sunny days that they almost blind the viewer. White glazed-tile roofs contribute to the luminous quality of the building. The opulence of these materials is complemented by the richness of the architectural and sculptural decoration and the intricacy of its allegorical theme.
