The City and County of Denver has a formal historic designation program that establishes Denver landmarks. These are designated by ordinances of Denver's city council. The first three sites so designated, on January 10, 1968, are the Emmanuel/Sherith Chapel, (destroyed by fire in 1977), and the Governor's Mansion. The list includes a sublist of historic districts.
