Red-orange sandstone from Redrock Canyon in Colorado Springs faces and trims this nearly square edifice. The presiding element is a 136-foot square belfry, with tall, thin lantern openings topped by round arches. A cross-gable roof covers the three-story church. The carved exterior sandstone, stained glass windows, and golden oak interior wood-work are adorned in floral motifs reminiscent of Art Nouveau. Unfortunately much of the exterior sandstone trim has been lost, leaving defoliated stubs.
As is typical of Presbyterian churches, few religious images appear in the interior, which resembles that of an opera house. The sense of theater is enhanced by curved seating rows, balconies, and boxes, a sloping floor, and two false fireplaces. Ranks of brightly painted organ pipes are augmented by simulated ones, their effect enhanced by three arches. The basement has been converted to a shelter for the homeless and an exhibition space with a display on the church's history since its founding in 1860.
