Small Wat South of Pattaya

[sunny6301]

I was wondering if someone might know the name of a small Wat close to Pattaya I used to visit years ago. As you leave Pattaya and start heading south down Sukhumvit (about 5km?) you turn left and continue about 1km. You then climb up wooden steps to a small area where blessings took place. It had almost a tree house feeling to it.

There was a very elderly Monk that I saw 2000-2003 and a few years later I returned and he had passed away. His body was mummified and encased in glass. I felt a very special connection to this Monk and feel embarrassed to not even know his name or the Wat. Looking at Google Maps with the street pics it might be Wat Huai Yai, but not sure.
