The city state of Ayutthaya in time, grew to become an important trade player in south-east Asia. Trade was vigilantly controlled by the
Ayutthayan Court. Customs houses were established in the cardinal directions around the city along the important waterways with a double function:
control of persons and goods, and most important for the court, collect taxes. There were four main customs posts called the "
Royal Customs Posts
(The "Tabanque ou Douane"on a French map)
Footnotes:

(1) Simon de La Loubère wrote regarding the customs house at the mouth of the Chao Phraya River: "The King’s Ambassadors arrived thus
within two Leagues of Siam, at a place which the French called the Tabanque; and they waited there eight or ten days for the time of
their entrance into the Metropolis. Tabanque in Siamese signifies the Custom House: and because the Officer’s House, which stands
at the Mouth of the River, is of Bambou like all the rest, the French gave the name of Tabanque to all the Bambou houses where they
lodged, from the name of the Officers House, which they had seen first of all."

(2) Serfs or Phrai were neither slave nor free, but commoners which served a master periodically with unpaid labour. [2]
(3) Gunnel or gunwale is a nautical term - the top of the side of a boat or the topmost plank of a wooden vessel. It was called as thus because guns
were mounted on it.
(4) Traditional Thai unit of length equal to 2 meters.
