In 1657, octroi was imposed in larger Danish cities which changed the layout and face of Aarhus over the following decades.
The city ranks as the 92nd largest city in the European Union, and as number 234 among world cities. Aarhus is the principal industrial port of the country in terms of container handling and an important trade hub in Kattegat.Major Danish companies have based their headquarters here and people commute for work and leisure from a wide area in Region Midtjylland.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".Parts of the ramparts are still in existence today and can be experienced as steep slopes at the riverside and they have also survived in some place names of the inner city, including the streets of Volden (The Rampart) and Graven (The Moat).
Aarhus grew to become one of the largest cities in the country by the early 16th century.In 2010, the city council voted to change the name from "Århus" to "Aarhus" to strengthen the international profile of the city. Certain geographically affiliated names have been updated to reflect the name of the city, such as the Aarhus River, changed from "Århus Å" to "Aarhus Å".It is still grammatically correct to write geographical names with the letter Å and local councils are allowed to use the Aa spelling as an alternative.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.The inner urban area contains 269,022 inhabitants (as of 1 January 2017 The history of Aarhus began as a fortified Viking settlement founded in the 8th century and with the first written records stemming from the bishopric seated here from at least 948.
