The largest postbox in Thailand

Betong’s original giant postbox stands on the corner of Sukyang Road at the Clock Tower intersection, in the middle of Betong town centre. Built from reinforced concrete in 1924, it measures about 140cm around and 320cm tall including its base — a genuine post box, not a replica, and it still accepts mail today.

Sanguan Chirachinda, Betong’s postal and telegraph master and mayor at the time, had it built before the outbreak of World War 2. He fitted a radio transmitter on top to relay news broadcasts to the district’s residents, a practical fix for a town far enough from Bangkok that information otherwise travelled slowly. That transmitter housing is still visible crowning the postbox.

Insider Tip: Betong now has two giant postboxes, so don’t stop at the first one you find. A newer, taller postbox — about 9 metres — stands separately at the community hall, also on Sukyang Road. Locals and tour groups treat both as photo stops, but only the 1924 original at the Clock Tower is the historic postbox with the transmitter.

Watch out: Despite the “largest in Thailand” name, this isn’t a certified world record — Guinness recognises a mailbox in Ube, Japan, as the world’s largest. Betong’s is a genuine local landmark and a fun photo, not a record holder.

Betong itself is Thailand’s southernmost town, tucked into the mountains against the Malaysian border, and the giant postbox has become one of the handful of images — alongside the town’s clock tower and its Yunnanese street murals — that visitors use to mark having made it this far south. It’s an easy, free stop rather than a destination in its own right.

Entry is free and there’s no fixed viewing time — most visitors spend a few minutes here on a walk around Betong’s town centre, easily combined with the Betong Clock Tower at the same intersection and the street art around town.
