Situated in the center of Thailand, Nonthaburi is one of the Five neighboring provinces of Bangkok which are Nonthaburi, Samut Prakan, Nakhon Pathom, Samut Sakhon, and Pathum Thani.

Covering an area of 622 square kilometers and separated into 2 parts by the Chao Phraya river, Nonthaburi is administratively divided into 6 Amphoes: Mueang Nonthaburi, Pak Kreat, Bang Kruai, Bang Yai, Bang Thong and Sai Noi. The long history of Nonthaburi dated back 400 yearsto the era of Ayutthaya Kingdom.

Firstly known as Tambon Ban Talad Khwan and noted for its fertile soil and plentiful water where a lot of orchards nest along side the Chao Phraya River, this tambon has been promoted to Nonthaburi City in 1549 under the reign of King Mahajakrapat. In 1665, King Narai the Great had noticed that the river has changed its own route and it might consequently have a negative effect to the city’s security.

Hence, the fortifications have been established at the delta of Om River where the city pillar has been build as the symbol of the new foundation of Nonthaburi.
