Astrodome nicknamed the 'Eighth Wonder of the World'

When it opened in 1965 the Houston Astrodome was widely promoted and nicknamed the 'Eighth Wonder of the World' due to its size, dome design, and engineering. The marketing slogan was used in contemporary press and promotional materials to highlight the stadium's novelty as one of the first major domed, multipurpose sports venues. The Astrodome's nickname remains a commonly cited part of its history.
