According to the legend, Khun Inthapramun was a revenue officer who secretly embezzled the government tax to build this reclining Buddha image as a holy object. When the King asked how he obtained the fund from, Khun Inthapramun did not reveal the truth because he was afraid that his merit from building the image would be passed on to the King. He was finally sentenced to death. And the temple was then called Wat Khun Inthapramun.
