 Most such stadiums were built in the relatively plain brutalist and international styles popular at the time, which fell out of fashion in the 1980s.Furthermore the "concrete donut" design made the stadium feel too enclosed and cut off panoramic views of the stadium's aesthetic surroundings (waterfront, skyline, mountains).The suburban locales of many multipurpose stadiums (as well as other sport-specific stadiums also built there) were also a focal point for criticism.
