In form it is a symmetrical quatrefoil with a vast circular central space that can seat some 6,000 persons. The 23m-high dome is topped with a lantern in steel and glass. The Centennial Hall is a pioneering work of modern engineering and architecture, which exhibits an important interchange of influences in the early 20th century, becoming a key reference in the later development of reinforced concrete structures.<ref>http://whc.unesco.org/en/list/1165</ref>
