Phra Kaeo (Thai: พระแก้ว, in Thai pronounced as /pʰráʔ kɛ̂ːw/), sometimes written as Phra Kaew, is a tambon (subdistrict) in Phachi District, the eastern part of Phra Nakhon Si Ayutthaya Province.
Phra Kaeo is a canton that is the passageway of the Northern Railway Line (together with the Isan Railway Line). In the 18th century, it used to be a route back from Vientiane of the Somdet Chaophraya Maha Kasatsuek (later King Rama I)'s army. He had just finished the war and brought back the Phra Kaeo Morakot (Emerald Buddha; commonly referred to as Phra Kaeo) together. He and the Buddha image stayed overnight here before going back to Bangkok. Since then, the quarter where he rested and temporarily enshrined the Phra Kaeo Morakt, hence the name "Phra Kaeo".
The result of the division of the new administrative area make Phra Kaeo Railway Station and Wat Phra Kaeo (the place where the Phra Kaeo Morakt was enshrined was later built as a temple) belonging to the neighbouring Krachio.[1]
Phra Kaeo is the western part of the district. Most of the land is clay with lowlands.
Adjoining areas are (from the north clockwise) Phai Lom in its district and Ban Chung in Nakhon Luang District, Krachio in its district, with Ban Chung in Nakhon Luang District.
The entire area of Phra Kaeo is under the administration of the Subdistrict Administrative Organization (SAO) Phra Kaeo.
The seal of SAO Phra Kaeo shows Phra Kaeo Morakot in meditating posture along with the ears of rice adorned as a frame. Lower part is a handshake symbol.[1]
The area also consists of seven administrative muban (village).[2]
