Marienberg (sometimes misspelled as Marienburg) is a town located near the mouth of the Sepik River in Marienberg Rural LLG, East Sepik Province, Papua New Guinea.
[1] In 1913, in what was then German New Guinea, missionaries of the Catholic Society of the Divine Word established a settlement here.
[3] To facilitate this, one the first railways in the country was built to transport timber from the river to the sawmill.
[5] Bombing and subsequent re-occupation of the town by Allied forces led to the destruction of the sawmill, houses and church constructed there.
Shortly before independence in 1975, labor disputes led to the mismanagement and decline of the business and ultimately all industry ceased there.
