Wat Ratcha Orasaram Ratchaworawiharn is a first class royal monastery or Ratchaworawiharn. The temple is ancient, was built since the Ayutthaya period. Its original name was Wat Chom Thong. King Rama II renamed the temple to Wat Ratcha Orot, which means the temple was renovated by Ratcha Orot (the King's son) who was later crowned King Rama III. At that time the prince held the position of Prince Chetsada Bodin. He was the commander who led the Thai army to engage the Burmese army in Kanchanaburi Province. On the first day of his march to war his route passed from Bangkok Yai Canal, (Bangluang Canal today) to Khlong Dan (Dan Canal). He reached this temple and stayed there overnight. He officiated a religious ceremony called Khon Thawan (Brahmin's Ceremony - blessing to warriors who are going to war) The abbot of the temple had calculated an auspicious to the campaign and he told his predict to the Prince, that the Prince should win the war and come back safely. The Prince promised that, if he had victory in the war, he would come back to renovate the temple. After the Prince had won the war, he ordered the entire temple restored. Because he favored Chinese style art, the architectural and artistic work for the temple's restoration was a combination of Thai and Chinese styles, called The Royal Favored Art. The harmony of the Thai and Chinese styles can be seen in both the Wiharn (the Sermon Hall) and Ubosot (The Ordination Hall) of the Reclining Buddha. This was the first temple to be built without the typical Thai decoration on the roof of the Ubosot and Wiharn. By around the temple
