Porto Amboim is a port town in Angola with a population of 65,000; it comprises an area of 4,638 km². It is connected by an isolated 123 km 610mm narrow gauge railway to Gabela, albeit closed in 1987 due to the civil war and to the abandonment of most coffee plantations, the biggest source of revenue from Gabela. Originally Porto Amboim was known as Kissonde, a small village later colonized in 1587 by the Portuguese naming it Benguela and later Benguela Velha (Old Benguela) due to the creation of another village today known as Benguela. In 1923, the name was changed to Porto Amboim.
