Langenæs is delimited by the streets Søndre Ringgade, Skanderborgvej, Marselis Boulevard and the valley of Brabrand Ådal.

Langenæs was built in the 1950s as a planned neighborhood of apartment complexes with the intention of testing new architectural ideals and methodologies.

The neighborhood is characteristic for its time when the ideal was open city blocks with adjacent green spaces.

The oldest parts of Langenæs lies along the edges as traditional and mixed early to mid 20th century developments.

Langenæs was later part of the Havreballegaard and Marselisborg estate in Viby parish for 700 years, before it was bought and annexed by Aarhus City Council in 1899.
