The Largest Mail Box in Thailand used to be located at the Bell Tower intersection of Betong. It was built in B.E. 2467 before World War II as the communication post for the townspeople, through the radio implanted on top of the box, and the mail slot below it. At present a new box had been built in a larger size (nine metres tall), and is located at the City Convention Hall (Sala Prachakhom). The new mail box attracts a large number of tourists who come to take the photograph.
