Quite a mouthful, so the locals call it Wat Chaloem.
Located on the west bank of the Chao Phraya River. The area was once home to a fortress known as Pom Thamthim which was built by King Narai in 1665. The fort was mostly demolished in order for the wat, which was ordered by King Rama III in honour of his mother and grandparents, to be built. The wat is certainly worth visiting as the setting is comfortable and the wat lacks the glitz that is laid on so heavy at some of Bangkok's other wats.
The main temple comes complete with welcoming red carpet and photos of the King who visited in January 1993 and the seated Buddha proudly wears a sash which was a gift from the King. The detailed designs on the walls were hand-painted by Chinese artists and the exterior doors and window shutters display cheerful rabbits. There are a few other Chinese influenced temples on the premises within the peaceful grounds. To the north of the main compound is the monk's residential section. The compound sports a somewhat surreal artificial garden and the real treat is the adjacent park. Tranquil, clean and well maintained with lakes, trees and lots of green, this is your spot to relax.
How to get there
To reach Wat Chaloem, catch a barge across the river from the Nonthaburi pier for 2B, then jump on one of the many waiting motorbikes for 6B. Despite how it may look from Nonthaburi town, you cannot walk to the temple along the river bank.
