During the 'Arnsberg exile' of the Cologne cathedral treasure (1794-1803), the relics of the Three Kings were temporarily housed here.
Arnsberg was first mentioned around 800 in the Carolingian urbans of the Werden Abbey near Essen. In the 11th century it was raised to the status of a county and later became the capital of the Duchy of Westfalen.
