The airport is known for its extensive public art collection
Denver International Airport (DEN) is known for its extensive public art collection, cultural exhibits, and iconic architecture.

When the airport opened in 1995, its art collection was heralded as one of the most innovative airport art collections globally. Today, the permanent art collection at DEN consists of 33 public artworks by local, national, and international artists.

One of the most famous artworks at the airport is the Blue Mustang statue, also known as Blucifer, for its bright blue colour and glowing red eyes. This 32-foot-tall sculpture of a horse with a demonic appearance was created by Luis Jiménez and unveiled in 2008.
