Redoubt from 1664 In 1664 General Rüsenstein raised a timber redoubt on Festningsholmen by Akerøya to bar the approach to Fredrikstad. The fort held up to 27 guns, was never taken in battle, and was in the end demolished by its own side.

Lit 1827 It began in 1827 with a single pilot keeping a light on the islet by agreement with the harbour commission. A century later, Heggholmen became the first lighthouse in Norway with electric light. Around it worked an island of linseed oil, soap and its own school.

Sanatorium 1885–1926 From 1885 to 1926 a sanatorium on Bleikøya treated children with glandular tuberculosis. The author Oskar Braaten was among the patients. When it closed, the cabin people took over, under rules just as strict today.

Light since 1837 The name Steilene comes from the execution ground: the executed were set up here on stake and wheel, in sight of every ship bound for Christiania. Today a lighthouse from 1837 stands on the outermost islet, and the keeper's house is yours to rent for a night.

Opened 1927 Gressholmen is its own name: grazing land out in the fjord. Then the aircraft came. From 1927 this islet was Oslo's airport, with a Berlin route from opening day, and the hangar still stands.

15 April – 15 September From 15 April to 15 September, open fire is banned in uncultivated land, and an island is uncultivated land. What the rule actually says, the exception it gives you, the rock-slab rule that has no season, and the two islands with fire sites you may use all year.
