The municipality of Tromøy was established on 1 May 1878 when the municipality of Austre Moland was divided into three separate municipalities: Tromøy (population: 2,320), Barbu (population: 4,874), and Austre Moland (population: 2,524). The municipality of Tromøy included several smaller islands, including Merdø, Skilsø, and Tromlingene.
On 1 January 1992, the municipality of Tromøy was incorporated into the municipality of Arendal, along with Moland, Øyestad, and Hisøy. Prior to the merger, the municipality had a population of 4,711.
Tromøy is known for having once hosted many Viking kings. According to the Ynglinga saga, Harald Granraude, the King of Agder, had his headquarters at Tromøy. It also says that his daughter, Queen Åsa Haraldsdatter, took her one-year old son, Halfdan Svarte back to Tromøy after the death of Gudrød Veidekonge. There are several place names in Tromøy derived from the Viking era including Kongshamn and Hove.
Hove is an area located on the south-western part of Tromøy which has easily cultivated, self-draining soil and was therefore a convenient place for early agriculture. The first recorded cultivation of potatoes in Norway is believed of have occurred at the Hove farm (Hove gård) which was one of the most significant estates in Tromøy. In 1757 the owner, Nils Mathiasen Aalholm, observed in his garden diary (Nils Aalholms hagedagbok) that potatoes were being cultivated on his farm.
World War II
During the Occupation of Norway by Nazi Germany (1940-1945), the Germans had an anti-aircraft school at Tromøy (Feld Flakartillerie-schule 50) from 1941-1944 at a camp built on the Hove farm. The camp was built for 1,500 men. There were 3 radars at the island and supposedly four 88 mm anti-aircraft cannons. Construction of a 200-metre (660 ft) airstrip was begun. Most of the camp's buildings, including the airstrip which never where completed, are still there today, along with a bunker (R618) of unknown purpose. The bunker is currently undergoing restorations (2007) but work has been halted due to an ownership dispute. The German military used 75 buildings in the area, most of them built during the war.
