In 2017, Aarhus has been selected as European Capital of Culture along with Paphos in Cyprus.With the Danish spelling reform of 1948, "Aa" was changed to "Å".
In the 900s an earth rampart for the defence of the early city was constructed, encircling the settlement, much like the defence structures found at Viking ring fortresses elsewhere.
The rampart was later reinforced by Harald Bluetooth, and together with the town's geographical placement, this suggests that Aros was an important trade and military centre.
Some Danish cities resisted the new spelling of their names, notably Aalborg and Aabenraa.
Århus city council explicitly embraced the new spelling, as it was thought to enhance an image of progressiveness.
; officially spelled Århus from 1948 until 31 December 2010) is the second-largest city in Denmark and the seat of Aarhus municipality.
It is located on the east coast of the Jutland peninsula, in the geographical centre of Denmark, 187 kilometres (116 mi) northwest of Copenhagen and 289 kilometres (180 mi) north of Hamburg, Germany.
As the industrial revolution took hold, the city grew to become the second-largest in the country by the 20th century.
Today Aarhus is at the cultural and economic core of the region and the largest centre for trade, services and industry in Jutland.
Whichever spelling local authorities choose, most newspapers and public institutions will accept it.
Some official authorities such as the Danish Language Committee, publisher of the Danish Orthographic Dictionary, still retain "Århus" as the main name, providing "Aarhus" as a new, second option, in brackets.
The city gates funnelled most traffic through a few streets where merchant quarters were built.
