Chumphon Gate is built from large laterite stones and bricks, which are covered with plaster, and has a watchtower made of wood, with a tiled roof decorated with ngao, bai raka and chofa.

The former city gate is today located in the center of Nakhon Ratchasima. It was built in 1656, during the reign of King Narai, who commanded that a strong city wall be built.
