Aarhus (, US also , Danish: [ˈɒːˌhuˀs] ; officially spelled Århus from 1948 until 1 January 2011) is the second-largest city in Denmark and the seat of Aarhus Municipality. It is located on the eastern shore of Jutland in the Kattegat sea and approximately 187 kilometres (116 mi) northwest of Copenhagen. Dating back to the late 8th century, Aarhus was founded as a harbour settlement at the mouth of the Aarhus River and quickly became a trade hub. The first Christian church was built here around the year 900 and later in the Viking Age the town was fortified with defensive ramparts.
