East of the main temple area is a large squat building that sits in a large pond. The structure is labeled Stupit That Phanom in large Thai letters, but there's no other information about what it is. There are two bridges across the pond to it, but the gates on both were closed and locked.
The temple is the center of an annual festival which starts on the 10th day of the third lunar month and runs for a week. The estimated date for the next festival is 3 March 2016.
