It stands on a wide base measuring 13 meters by 13 meters, reaching a height of 45 meters from the ground to the stupa's apex. This stupa showcases applied art and was constructed in 1987 to house the sacred relics of the Buddha and revered Arahants, such as Phra Siwali, Phra Upa Kut, and Phra Ongkuli Malah. Every year, on Makha Bucha and Visakha Bucha days, grand ceremonies are held to perform sacred water rituals, attracting many devotees.
