According to the "In–Chan–Mun–Kong" legend of the shrine, Thai locals believed that the construction of the shrine required the sacrifice of four people after the proclamation of the words ""in–chan–mun–kong"" all over the city (""in"" from the north, ""chan"" from the south, ""mun"" from the east, and ""kong"" from the west). Anyone who responded was captured, brought to the ceremonial location, and buried in a hole. Their spirits would guard and protect the city. This is only a myth and is not recorded in the chronicles.
