Occupying a full, tree-shaded block, this Neoclassical edifice has a metal-clad dome and many protruding bays. The formal, three-story design is executed in beige-white brick, with terracotta for quoins, keystones, and trim. The pedimented north entry with its ornate medallion and exaggerated keystone is flanked by pairs of columns with Ionic capitals. Stained glass skylights brighten the four-story interior rotunda, restored in 1984, returning luster to its Colorado Yule marble and ornate tile floors, its golden oak trim, wrought iron staircase, and brass railings. The interior restoration also revived many rich classical details, replaced 4,000 broken floor tiles with hand-cut duplicates, and refurbished the original golden oak jury chairs.
Denver architect John Huddart, who trained in England and as a draftsman for Frank Edbrooke in Denver, designed government buildings over a span of four decades in Colorado, Nebraska, Oklahoma, and Wyoming, including a number of Colorado county courthouses.
