History
The original town of Arendal was quite small in size. Originally, the area surrounding the small town was part of Østre Moland Municipality. In 1878, the area immediately surrounding the town was separated and became the new Barbu Municipality. In 1902, all of Barbu Municipality was merged into the growing town of Arendal, vastly increasing the size of the town.
