Prachuap Khiri Khan Provincial Center


The Provincial seat of Prachuap Khiri Khan, or Muang District อำเภอเมืองประจวบคึรีขัน is the  provincial government administration center, and thus where many provincial government offices are located.

The area itself is in the heart of what is Thailand’s narrowest stretch between a coastline and an international border, the narrowest stretch being only 12 kilomters from the Gulf of Thailand coastline to the Myanmar border. This stretch is located in the Klong Wan sub district of Prachuap Khiri Khan muang district, just outside of the center.

The entire muang district parameter spans an area of 844 square kilometers and is home to 83,290 residents.

Economic activity gravitates around the central Municipality.


Officially announced as a municipality and provincial center in 1935 during the reign of King Rama VIII, Muang Prachuap Khiri Khan Municipality initially covered an area of less than five square kilometers.In 1967, during the reign of King Rama IX, the municipality officially annexed neighboring lands, expanding to its current 14 square kilometers.
