Hidden away in Issan, in the Nakhon Ratchasima province is a historical park home to one of the most important Khmer Temples of Thailand.
The temple is unique because despite the Khmers being Hindu at the time. It was actually built as a Buddhist temple. The temple reminded me a lot of Angkor Watt in Cambodia. Just without the thousands of tourists. In fact, on my visit to Phimai, I recall counting about 6 other Western people there besides myself. Which to me makes it a place to visit off the beaten track. A unique place with a lot of history about Buddhism, Hindu and the Khmer ruling in Thailand.
You can still see the general layout as to how the temple used to work. Some of the building has fallen apart but they were trying to rectify it when I visited. From its unique build to the crazy story-telling carvings in the stones. The Temples of Phimai is a great day to put in if you are visiting the North East of Thailand. A place where it is rare to see any foreigners.
