Sitting commandingly atop Capitol Hill, this stately neoclassical government building looks out across the grand Civic Center Park. The ornate interior befits such a grand building, and visitors can join free tours that depart every 45 minutes.
Construction began in the 1890s from locally quarried rose onyx (Beulah red marble) and in 1908, to celebrate the Colorado gold rush, the superb dome was covered in 200 ounces of gold leaf. The 13th step sits exactly a mile above sea level.
