Wat Nak Prok, วัดนาคปรก, is located in Khwaeng Pak Khlong Phasi Charoen, Phasi Charoen District, Bangkok. The temple was presumably built in 1748 (B.E. 2291) in the Ayutthaya period. It is said that a Chinese merchant called Phuk was the contributor of the temple buildings. The Phra Wihan (Sermon Hall) was dedicated to his Thai wife and the Phra Ubosot (Ordination Hall) was dedicated to himself. Buddha images were later enshrined in the Phra Wihan and Phra Ubosot. The temple is named Wat Nak Prok (or Wat Nakprok) after the most sacred Buddha image made of bronze in the posture of Meditation under the shelter of a seven-headed serpent (Nakprok) made of mortar and enshrined inside Phra Wihan. The Phra Ubosot, originally built in Ayutthaya style is now being modified in accordance with a later restoration that occurred during the reign of King Rama 3 or King Rama 4.
