Samut Sakhon province
Samut Sakhon was formerly called Tha Chin probably because, in the old days, it had been a trading port dealing with a vast number of Chinese junks. In 1548, a town named Sakhon Buri was established at the mouth of the Tha Chin River. It was a centre for recruiting troops from various seaside towns. The name of the town was changed into "Mahachai" when Khlong (canal) Mahachai was dug in 1704 to join the Tha Chin River at the town. Later, the town was renamed Samut Sakhon by King Rama IV but it is still popularly called "Mahachai" by the villagers.
Samut Sakhon is located 30 kms. from Bangkok. The province occupies a total area of 872 square kilometres and is administratively divided into 3 districts: Muang Samut Sakhon, Krathum Baen, and Ban Phaeo. It is a major fishing port and also the biggest producer of brine salt.
Etymology
The word Samut originates from the Sanskrit word Samudra meaning ocean, and the word sakhon from Sanskrit sagara meaning lake.

Geography
Samut Sakhon is located at the mouth of the Tha Chin Klong river, a distributary of the Chao Phraya river, to the Gulf of Thailand. At the coast to the sea are many fields used for sea salt production.
History
The oldest name of the area is Tha Chin, probably referring to the fact that it was a trading port where Chinese junks arrived. In 1548 the city Sakhon Buri was established, and was renamed in 1704 to Mahachai after the khlong Mahachai which was dug then and connected with the Tha Chin river near the town. It was renamed by King Mongkut to its current name, however the old name Mahachai is still sometimes used by the locals.
