I like this temple. It has unique and beautiful designs with the iconic huge Red Giant Swing at the front.
When I was there, it was quite busy and there were even few people who were doing Spiritual Retreats inside the temple. The temple is close to Bangkok City Hall and close to Khao San Rd.
The Buddha inside is beautiful. The walls are all covered in beautifully painted pictures depicting Buddha's stories. You can also make donations for various things, like electricity, books, scholarships etc Visit this temple!
