The structure is an adapted Lanna-style pagoda, designed by Mom Rachawong Mitrarun Kasemsri, an architect of the Royal Palace. It draws inspiration from the Phra That Kophaku at Wat Pa Sak in Chiang Saen District, Chiang Rai Province. The pagoda consists of three levels: On the first level, there is a bronze statue of Somdet Ya, which is life-sized and showcases her in full royal regalia in a seated position. The second level houses the royal ashes of Somdet Ya, while the third level is dedicated to the sacred relics of the Buddha. The site is open daily from 6:00 AM to 5:00 PM, and there is no admission fee.
