Midtbyen is part of district Aarhus C, with postal code 8000, together with Vesterbro, Nørre Stenbro and Frederiksbjerg and it has a population of 55,000. The stream of Aarhus Å flows through Midtbyen and adds to the areas' distinct charm. The waterway was covered by roads for many decades, but has recently been opened up again.
