King Mongkut gathered the people of three towns—Bang Nangrom, Kui Buri, and Khlong Wan—and resettled them in the rebuilt city. At the same time, he renamed a portion of what is now Trat province and Koh Kong province in Cambodia "Patchan Khiri Khet". The name was chosen to rhyme with "Prachuap Khiri Khan" on the opposite side of the Gulf of Thailand at the same latitude.
