Denver Civic Center could be on its way to becoming a National Historic Landmark — the first of its kind in the Mile High City.

Denver Mayor Michael Hancock testified in support of the designation at the Spring 2012 National Park system advisory board landmarks committee meeting on Tuesday, according to a news release.

“Civic Center serves as the keystone for the entire Denver Parks system and sits literally where the city’s cultural, community and commercial realms converge,” Hancock said.

The designation would include Civic Center park, Veteran’s Park, the McNichols Building, the City and County Building and the Colorado State Capitol.

The Empire State Building, the Alamo and the Library of Congress are currently designated as historical landmarks, according to the release.

Recommendations for Civic Center will go to the National Park Service advisory board May 22 and 23. The board will then advance their recommendations to U.S. Department of the Interior Secretary Ken Salazar, who would officially designate the site a landmark.
