Østerå River

The Østerå River is a small waterway that winds through the northern part of the Aalborg area, flowing across the landscape in sections. Part of the river runs above ground while other stretches flow underground beneath the modern city.

During medieval times, the Østerå River served as Aalborg's harbor and supplied the growing settlement with water and power. In the late 1800s, the waterway was redirected into underground pipes to make room for city expansion.

The river shaped Aalborg's growth, and its legacy appears in street names like Østerå and Aagade that still mark the city today. These names reflect how much the waterway mattered to local life.

The banks feature walking paths and open spaces where visitors can spend time outdoors. These areas work well for casual strolls, especially during dry weather.

The river largely disappeared from view after being channeled underground in the 1800s. Today visitors can still spot places where the water emerges back at the surface from the pipes.
