Wat Pha Namthip Thep Prasit Wararam in Roi Et includes the stunning or Maha Chedi Chai Mongkhon or the Chai Mongkhon Pagoda. The pagoda is simply amazing. Pictures cannot really show or convey how stunning it is, but I've attached a few.
I highly recommend a visit.
The temple is reached driving up a slightly rugged and winding road. Along the way, there are stalls selling somtam, roasted chicken and grilled fish.
At 101 meters high and rising from a 101 meters wide and 101 meters long base, this pagoda truly is one of the most beautiful and largest pagodas in Thailand. Lord Buddha’s relics are enshrined in this five-storeyed pagoda. The view of the surrounding landscape can be enjoyed from the roof.
