The appearance of Denver International Airport uses 130- to 150-foot tall roof peaks meant to reflect the snow-topped mountain peaks of the region, but unfortunately most don’t think the tent-looking peaks are even close to as beautiful as the actual mountains.
DIA is ugly enough to those across social media to get it ranked among the nation’s ugliest buildings.
According to researchers at Buildworld, the recognizable white tent-poled roof at Denver International Airport has apparently instigated widespread public condemnation and now finds itself among the Top 10 Eyesore Buildings in the U.S.
Buildworld set out to find the buildings and structures around the world that people often described as ugly online. The writers did this by rifling through design-themed tweets posted about each building before using a sentiment analysis tool to break down just how many were negative.
DIA is the only airport on the list, joined by government buildings, sports arenas, a casino and a New York City skyscraper. See the full list here.
