The main attraction for the Erawan Museum is the massive three headed elephant 250 tons in weight, 29 meters high, and 39 meters long. I thought it was pretty impressive. It's not exactly in the center of town. I think the fastest way is to take the BTS to Bearing (40B) then take a taxi to the museum (50B).
This is the ceiling inside of the elephant.
More interior shots inside the elephant.
This display was near the window that had a good view of the highway (hence no picture).
Some of the artifacts in the small museum in the base of the statue.
One ritual offering involves setting a lotus flower adrift in the moat surrounding the statue.
The rest of these photos were taken in the garden and stream surrounding the statue.
