The Memorial Coliseum was an architecturally significant building of the Mid-Century modern style. Extremely well constructed, its footings were anchored into the original seabed, well below the 1940s fill. The curved roof contained 260 tons of structural steel in a lamella space frame (diamond shape design) with a thin concrete cover. This strong, yet light roof structure allowed for the barrel-shaped 224-foot unsupported span, which was the world’s longest when it was built. As an additional plus factor, this kind of construction keeps insurance costs low and maintenance over 40 years is lower than in traditional buildings.<br>
