Four Mile House (oldest standing structure in Denver)

Four Mile House was constructed in 1859 as a stagecoach stop and ranch and is recognized as the oldest standing structure within the modern city limits of Denver. The house and surrounding acreage form Four Mile Historic Park, which preserves the building and associated frontier-era outbuildings and interprets the historic stage road. The park operates as a museum offering living-history programs about 19th-century transportation and agricultural infrastructure.
