During the reign of King Rama VI, Wat Phra Pathom was renovated and later the temple became the royal temple of King Rama VI. Within the monastery compound, there are various interesting historical items, including the Phra Ruang Rodjanarith ,an image of Buddha bestowing pardon, is enshrined in a vihara located to the North and in front of Phra Pathom Chedi.
