The gold-domed State Capitol's 13th step is exactly one mile above sea level — and free tours of the building and its extraordinary stained glass are available daily.
Why It’s Worth Your Time
The Colorado State Capitol (1894) is Denver's most recognizable landmark — a neoclassical dome covered in 200 ounces of Colorado gold leaf. The 13th step on the west entrance is engraved 'One Mile Above Sea Level.' Free guided tours run daily and cover the building's extraordinary stained glass portraits of Colorado pioneers, the Senate and House chambers, and the observation deck with sweeping Front Range views. The surrounding Civic Center Park is the city's most important public space, hosting outdoor concerts and food festivals throughout the year.
