Grant–Humphreys Mansion

The Grant-Humphreys Mansion is a neoclassical residence in Denver featuring a balanced facade, prominent columns, and carefully finished stonework throughout its exterior and rooms. The building showcases skilled craftsmanship in both its structural design and interior spaces.

James Benton Grant, Colorado's third governor, commissioned the building's construction in 1902 through the architectural firm Boal and Harnois. The residence reflects the architectural ambitions of wealthy industrialists during the early 1900s.

The mansion embodies the wealth of two prominent families: the Grants, who made their fortune in ore smelting, and the Humphreys, who prospered through oil production. Both families shaped Colorado's economic growth during the early 1900s.

The property is managed by the Colorado Historical Society and serves as a venue for weddings, events, and educational tours. Visitors should plan ahead and contact the site to arrange a guided experience.

The mansion once featured the tallest residential chimney stack in the country, a symbol of its first owner's industrial power. This striking structure demonstrated the Grant family's technological advancement and economic success.
