Wat Song Phi Nong (วัดสองพี่น้อง) Legend has it that Chao Sam, one of the three siblings, incited the other two siblings named Chao Ai and Chao Yi against each other for the throne. Both Chao Ai and Chao Yi died and Chao Sam became the ruler. Chao Sam then built one prang and one chedi for his late brothers.
