Phra Phuttha Narumit is a Buddha image dedicated to King Rama II, enshrined in the Vihara in front of the Great Prang of Wat Arun. The image is in the Subduing Mara posture, cast in metal and covered with gold leaf, showcasing the elegant and majestic style of early Rattanakosin art. King Mongkut (Rama IV) commanded its creation to serve as a memorial Buddha image for his royal father, King Rama II. The enshrinement of this image at Wat Arun reinforces the temple's significance as the representative temple of King Rama II and serves as a center of devotion to his memory.
