The tallest Mail Box in the world was established by Mr. Sanguan Jirajinda, Mayor of a small town called Betong in Thailand in 1924. It was made of reinforced concrete and was approximately 3 metres tall. Sanguan, who was a former postman built it at the age of 80 to be a symbol of communication of Betong and installed a radio broadcast on the top of the mail box for people to listen official news. The mail box is still in use.
This has, however, been superseded by another mail box of similar look constructed by Betong Municipality. The new Mail Box is three times taller at approximately 9 mts.
The new mail box attracts a large number of tourists.
