A Visit to Thailand’s Pavilion
The architecture of the pavilion is the first thing that visitors experience, and should reflect the theme of a Country’s contribution and its identity. For this reason, the pavilion, covering a total space of 2,947 square meters, has a form that is based on the center of the Thai rice farmers’ traditional hat, the "Ngob."
