The Phra Buddha Chinnarat image is one of the top venered Buddha images in Thailand. It is quite old - about 800 years and it is housed in Wat Mahatat which dates back to the 12th century.
To even find yourself on the temple-grounds is an overwhelming experience - especially so at time of sunrise or sunset when the gold-tiles on the roof and the gold on the Ayutthayan-style prang literally beams and glows in bright yellow!
Upon entering the building where the Buddha image is housed, you will be stunned by the incredible beauty of the real, original Buddha Chinnarat. I have seen the exact copy of this image in the "Marble Temple" in Bangkok and the effect the original image has on the viewer/visitor is amazing.
The temple interior is quite dark with no windows - however, the energy and glow from the Buddha image is so strong that you will feel like you are "bathed" in "divine light"....incredible.
I also recommend visiting the nearby Buddha image foundry (free - no admission) where one can see the age-old process of the "lost-wax" casting of Buddha images.
