The wat was built by King Chulalongkorn in 1878 AD in the style of a Christian cathedral near to his palace in Amphoe Bang Pa-in, near Ayutthaya. It stands on an island in the Chao Phraya river, and the approach is via a cable car. The architecture is in Gothic style, and has some good stained glass windows. The main image, which sits on a Christian-style altar, is called Phra Puttha Naruemon Thammophat. The Buddha relics are housed in the combined belfry and clock tower, which therefore approximates to a stupa. There is a stucco relief of the King's Great Seal, and a stained glass window portrait of the King, with the words Chulaloncorn : Rex Siamensis (Chulalongkorn, King of the Siamese) written in Latin. The temple is still active, and when we were there there was extra security as the heir to the throne was due at the palace the following day.
