Poso is the administrative capital of Poso Regency, Indonesia. It is the main port and transportation hub for the central-southern coast of Central Sulawesi. Its urban area is consisting of three subdistricts, Poso Kota, North Poso Kota, and South Poso Kota. Poso lies in the middle of the province on the shore of the Gulf of Tomini, right in the central part of Sulawesi island. With the total of population of over 40,000, it is one of the biggest and the oldest towns in the province. Poso began to develop as a small port town located at the mouth of the Poso River at the end of the 19th century—making it one of the oldest towns in Central Sulawesi, and its presence was considered important for the Dutch to control the southern region of Tomini in the early days of their arrival. Poso was the administrative center of :id:Landschap Poso|Landschap Poso, :id:Onderafdeling Poso|Onderafdeling Poso, and later :id:Afdeling Poso|Afdeling Poso during colonial times. In the midst of the World War II, the Japanese made Poso one of their military posts. Post-independence, Poso was chosen as the capital of the newly formed Central Sulawesi in 1948 before being moved to Palu in 1951. The central location of Poso has made it a stopover either from the north to the south, or from west to the east of Sulawesi. It is for this reason that the population of Poso consists of many different ethnicities, religions and backgrounds. People living in Poso are spread from the coastal area to the mountainous region, with the main sources of income being trade and services. Poso is crossed by Trans-Sulawesi National Highway and served by Kasiguncu Airport, linking it to other cities in Sulawesi such as Palu and Makassar.
