Wat Inthakin is an old temple with a large brick chedi south of the three Kings monument. It doesn't contain a building, but rather houses a modern roof to cover the ancient Buddha images, specifically Luang Phor Khao. It was once the location of the city pillar, known as Sao Inthakhin. Historically known as Wat Sadue Mueang the temple was abandoned as was the city during the Burmese occupation in 1775.
