Siam's display was a replica of Ben Chama Temple, in Bangkok. The 66 foot square building was situated between the Mexican and Nicaraguan pavilions. It was shaped like a Greek cross (four arms of equal length radiating from a center), it was crowned by a high pitched roof, with a concave ridge pole. This pole is terminated by the pointed ornament, which is seen on the temples of Siam. Each wing of the building had three gables, which rose one above the other, the ridge of each gable being crowned by the ornament mentioned. The building cost 10,000 dollars, but the entire pavilion and exhibits totaled 35,000.
Inside, the structure- a large room (and a 14 by 23 foot room used as offices), was decorated in green, vermilion and rich gold. There are no posts in the main room; it housed weapons, musical instruments and models of temples from the Royal Museum of Bangkok. the roof being carried on Siamese trusses. The room also sported staff decorations in a Siamese elephant motif. One noted portrait was a painting of the King, Queen and Prince of Siam.
The pavilion was surrounded by a small but beautiful garden.
