If you want to learn about the history of Chachoengsao through the exquisite and unique plasterwork, then you should take the opportunity to visit Wat Sampathuan at least once. You will be captivated by the sculptures that narrate the charming past of Chachoengsao in an interesting way. The abbot of Wat Sampathuan, Phra Puthirangsri Muneewong (Haw), conceived this project. The plaster reliefs are positioned on the south side of the old ubosot, illustrating the landscape of Chachoengsao and the surrounding village where the temple was built, as well as depicting the lives of people living along both banks of the Bang Pakong River. These works reflect every aspect of daily life, including clothing, transportation, tools, and everyday survival. The sculptor, Nai Sieng Ki, along with his four children as assistants, crafted these figures based on the abbot's descriptions, without any written designs provided. The origin of the name "Sampathuan" has a legend that recounts a peculiar event in the Bang Pakong River, where three holy monks—Luang Pho Sothorn, Luang Pho Wat Ban Laem, and Luang Pho To from Wat Bang Phli Yai—floated down from the north to the south. They surfaced in the Bang Pakong River near Baan Suan Prik. The three monks were carried against the current, and despite the villagers' attempts to pull them out, they failed. Eventually, all three monks sank beneath the water, leading the villagers to name the area where they floated against the current "Baan Sam Phra Tuan," which later evolved into "Sampathuan" as we know it today.
