Neighboring provinces are (from north clockwise) Phra Nakhon Si Ayutthaya, Pathum Thani, Bangkok, and Nakhon Pathom. Nonthaburi is the most densely populated province after Bangkok. The Bang Kwang Central Prison is in the province.

Geography

Nonthaburi is directly northwest of Bangkok on the Chao Phraya River. The province is part of the greater Bangkok Metropolitan Area. In most parts it is as urbanized as the capital, and the boundary between the two provinces is nearly unrecognizable. There is no forest area in the province.

History

Nonthaburi was declared a city in the middle of the 16th century. It was previously a village named Talat Khwan. During the reign of King Prasat Thong, a canal was dug to create a shortcut for the flow of the Chao Phraya. The river changed its flow into the new canal, which is still the riverbed today. In 1665 King Narai built a fortress, as the shorter river course was giving enemies an easier route to the capital, Ayutthaya. The town was then moved near the fortress.

From 1943 to 1946 the province was incorporated into Bangkok.

Symbols

The provincial seal shows earthenware, a traditional product of Nonthaburi. The provincial tree and flower is the yellow flame tree (Peltophorum pterocarpum).

The provincial slogan translates to "Grand royal mansion, renowned Suan Somdet, Ko Kret's pottery, famous ancient temples, tasty durians, and the beautiful government office". The royal mansion refers to Phra Tamnak Nonthaburi in Mueang Nonthaburi District, the former residence of Prince Maha Vajiralongkorn. Princess Mother Srinagarindra Garden (Suan Somdet) is a water garden with a statue of princess Srinagarindra in the Pak Kret District. The provincial administration building once received an award as the most beautiful such building by the Ministry of Interior.

Agriculture

Nonthaburi province is renowned for growing the best durians in the country. Durian has been a well-known fruit in this province for 400 years. The fruit is known as "Durian Non" which means durian from Nonthaburi province. It is also known as the most expensive durian in the world. There are six groups of Nonthaburi durian which are Kop, Luang, Kan Yao, Kampan, Thong Yoi, and miscellaneous. Most durian orchards are near rivers such as the Chao Phraya. This is because the soil next to the river is good for planting which is also good for durian trees. Many durian orchards have disappeared due to flooding and pollution. The price of durian Non depends on its group. Kan Yao is the most expensive, starting from around 10,000 baht up to 20,000 baht (or about US$600) for one durian. The Kan Yao itself is not easy to find in normal markets. The main reason for the high price is because it is rare. The recent flood in 2011 cleared out almost all of the durian trees in Nonthaburi, and only a few trees have been newly planted. Also, residential areas are expanding into agricultural areas.

Health

Nonthaburi's main hospital operated by the Ministry of Public Health is Phra Nang Klao Hospital. It is also the location of the largest psychiatric hospital in Thailand- Srithanya Hospital.
