There has been a temple fair at Phra Samut Chedi in Samut Prakan for the last 185 years. The temple buildings used to be on an island in the middle of the Chao Phraya River. But after the river was dredged in the 1950’s to allow container ships to reach the port in Bangkok the river gradually changed direction. The gap between the island and the bank silted up and it soon become part of the mainland. The annual temple fair is held every October at the end of the rainy season.
