Literary significance
The novelist Joseph Conrad made four visits to Berau, stopping at Tanjung Redeb, while employed as the first mate of the merchant vessel S.S. Vidar in 1887–1888. The geographical setting and the lives of the small number of European traders based in Berau made a profound impression on him, and the setting for three of his novels (Almayer's Folly, An Outcast of the Islands and the second part of Lord Jim) is loosely based on Berau. Conrad sometimes refers to the Berau river as Pantai and uses the fictional name Sambir to refer to Tanjung Redeb.
