I was driving around in Pathum Thani Province one day when I came across a temple with an intriguing name. It was called “Wat Chedi Hoi”. This basically translates as “The Shell Pagoda”. I went inside and found this Buddhist monument made from literally thousands and thousands of giant oyster shells. What is even more surprising is that this temple is to the north of Bangkok and the sea is about 60 kilometers to the south. Apparently, hundreds of years ago, this whole area used to be under the sea.
