One of Colorado's best-preserved Second Empire edifices is located on a two-block site. Lyman Robison, owner of mines in Cripple Creek and Leadville, built this 6,000-square-foot, three-story residence of native sandstone and pressed brick from the local Catlin brickyard. Wrought ironwork tops the cornice, while tall, narrow windows capped by ornamental lintels pierce the mansard roof. Two-story bay windows project from the east and west sides of the house, and a two-story porch supported by classical columns stretches across the front. The interior has three fireplaces, seven bedrooms, two bathrooms, a solarium, and a carved walnut staircase. On an expansive, well-landscaped, tree-shaded site beside the Arkansas River, the residence and its two-story carriage house have been restored, the latter as a restaurant.
