Biohuts at Aarhus Harbour
Hidden beneath the quay at Balticagade, Aarhus’ Biohuts turn a working harbour wall into a quiet experiment in marine restoration and urban biodiversity.
Tucked along the quays at Balticagade, the Biohuts at Aarhus Harbour are a small but fascinating window into urban marine restoration. These submerged “fish nurseries” act as protected hideouts and feeding stations for juvenile fish, mounted beneath the harbour’s edge. Interpretive information from the port’s biodiversity initiatives explains how these steel cages filled with shells and habitat structures help bring life back to hard‑edged docks, making this an educational stop for curious walkers, families and anyone interested in coastal ecology.

Local tips
- Visit in daylight and on a clear, calm day; with less wind and surface chop, it is easier to see the Biohut structures and fish activity in the water below.
- Combine a stop at the Biohuts with a longer stroll along Aarhus Harbour’s waterfront so you can experience both the industrial operations and the softer, eco-focused initiatives.
- Bring curiosity rather than gear; you do not need equipment, but children may enjoy a simple note pad to sketch what they imagine is happening below the surface.

Getting There
-
City bus from central Aarhus
From the city centre, use one of the regular city bus lines serving the harbour and Balticagade area; typical travel time is 10–20 minutes depending on traffic. A single adult ticket on local buses in Aarhus usually costs around 20–30 DKK when bought via ticket machines or apps, and buses run frequently throughout the day. From the nearest stop, expect a short, level walk on paved surfaces suitable for most mobility levels.
-
Cycling from Aarhus city centre
Cycling from central Aarhus to Balticagade typically takes 10–15 minutes along mostly flat urban streets and dedicated cycle paths, making it a straightforward ride for confident cyclists. The city has numerous bike rental options with daily prices often in the range of 80–150 DKK depending on the type of bicycle. The final approach runs along the harbourfront with smooth surfaces and good visibility, but be mindful of port traffic and changing weather conditions.
-
Walking from Aarhus Ø waterfront district
If you are already exploring the Aarhus Ø and inner harbour waterfront, reaching the Biohuts area at Balticagade on foot will usually take about 20–30 minutes at a relaxed pace. The route follows wide promenades and pavements with generally level ground, suitable for most visitors including families with strollers. There is no cost involved, and along the way you pass a mix of residential, cultural and port-related buildings that frame the working harbour environment around the Biohuts.

Harbour corners turned into underwater nurseries
Biohuts at Aarhus Harbour transform what would otherwise be bare, vertical quay walls into pockets of life beneath the surface. Installed along sections of the harbour near Balticagade, these robust cages hang just below the waterline, where their steel mesh frames are packed with shells, stones and artificial habitat modules. To a passer-by on the promenade, they may look like simple boxes anchored to the quay, but below the surface they function as miniature reefs, breaking up the otherwise smooth harbour walls. The concept is straightforward: give young fish somewhere to hide and feed in a port environment that is normally dominated by concrete and ship traffic. In Aarhus, the harbour authority has supported the installation of multiple Biohuts in cooperation with marine researchers, so this small area now acts as a pilot field for enhancing biodiversity in an intensely used working harbour.Fish restaurants and safe rooms under the surface
Inside the Biohuts, layered shell material and crevices create exactly the kind of cluttered micro-habitat that small fish seek out in natural coastal zones. Detritus and algae gather on the structure, attracting tiny invertebrates that become food for the fish. At the same time, the tight spaces between shells and mesh are too small for larger predators to enter, so juvenile fish can dart inside and shelter when danger looms. Over time, the cages become increasingly encrusted with marine growth, turning into busy little neighbourhoods. Crabs, shrimps and filter-feeding organisms join the community, and the Biohuts begin to soften the ecological impact of the harbour’s hard edges. For observers on land, this means that a previously anonymous stretch of quay now hides a quietly thriving underwater scene just a few metres away.A living laboratory for urban marine ecology
The Biohuts at Aarhus Harbour do more than offer refuge to fish; they also serve as a practical field site for studying how life returns to modified coastal zones. Researchers and educators can use the installations to monitor which species move in, how quickly the structures are colonised, and what difference they make compared to unmodified quay walls. This helps inform future waterfront projects, where ecological considerations are increasingly part of design decisions. Though the harbour remains a busy industrial setting with ships, cargo operations and traffic, sections around the Biohuts introduce a different narrative: that ports can both support commerce and act as stepping stones for marine restoration. For visitors, this adds a layer of meaning to an otherwise functional landscape and underlines Aarhus’ broader focus on sustainability.What you experience at the water’s edge
From the promenade at Balticagade, the experience is subtly educational. You hear the clink of rigging from nearby boats, the hum of port machinery and the slap of waves against the quay, while looking down at the water where the Biohuts hang. Depending on light and water clarity, you may glimpse the outline of the cages and the movement of small fish below. Information boards or signage connected to the harbour’s biodiversity program explain the idea behind the “fish kindergartens” and may include illustrations showing the interior and the species they support. The setting combines a working harbour atmosphere with a low-key exhibition feel, making it easy to pause during a harbour walk, reflect for a few minutes and then continue along the waterfront.Family-friendly learning in an everyday setting
Although modest in scale, the Biohuts are well suited to families, school groups and anyone seeking a short, meaningful stop rather than a full-scale visitor attraction. Children can stand at the railings and imagine the hidden “city” of fish below, while adults relate the project to wider themes of climate adaptation and nature-based solutions. No ticket or booking is needed, and the site blends seamlessly into the public harbourfront. In this way, the Biohuts at Aarhus Harbour demonstrate how small interventions can change the character of a city shoreline. A simple steel cage becomes a story about coexistence between industry and nature, and a regular quay becomes a place where people and marine life share the same address in more balanced ways.Iconic landmarks you can’t miss
