The Typewriter Topics report of the 1907 show:

Olympia is an exhibition and conference centre opened in 1886 and originally known as the National Agricultural Hall. It covered an area of four acres (16,000 m2). The Grand Hall, 450 feet in length by 250 feet in breadth, was said to be the largest building in the kingdom covered by one span of iron and glass.
