A New York City firm designed this courthouse in the Beaux-Arts Neoclassical tradition. It is faced with Turkey Creek white sandstone in smooth-faced ashlar over two-foot-thick brick walls. Pikes Peak granite is used for the foundation and the grand entry stairs.
On a landscaped full city block, the courthouse reigns over downtown Pueblo. The south and north elevations are distinguished by central and end bays with fluted Corinthian columns supporting dentiled pediments. Immense casement windows stretch from floor to ceiling, giving maximum light and a sense of spaciousness to the interior. The center bay is capped by a dome sheathed in copper with eight ocular windows.
In addition to onyx and marble floors and decorative bronze hardware and fixtures, the interior is distinguished by the stencil murals of J. Charles Schnorr depicting the history of the area. Schnorr's portraits of community leaders hang on the walls of the rotunda, the County Commissioners' Chamber, and the courtrooms.
