Poncan Ketek Island (Small Poncan Island) in Sibolga Bay was once the location of a fort, with British, Dutch, French, and American traders passing through. It is thought Stamford Raffles passed through before he moved to Bengkulu in southern Sumatra. From Bengkulu Raffles, after relinquishing the port to the Dutch, established the trade port that became Singapore. At some point between 1890 and 1920, there was a major fire in the city, which was presumably mostly built from wood from the surrounding mountains (shown partly denuded in the 1928 panorama below). After the Japanese invasion of Sumatra in 1942, a makeshift prison described as a "civilian camp" was set up at Taroetoengweg, in the city center, from 16 March to 4 May 1942. It first housed 10 "European" men from in and around Sibolga, who were then joined on April 24 by another 10 men from the island of Nias. On May 4 they were taken to the Native Secondary School for Boys in Pearadja (Taroetoeng), located in the mountains behind Sibolga.
