Den Gamle By

Den Gamle By—the Old Town—is an open-air museum in Aarhus founded in 1909 when architect Peter Holm and his team began moving historic buildings to the site, and it now contains 68 historic buildings from various Danish towns, spanning the period from 1660 to 1970 and presenting the full evolution of Danish urban domestic and commercial architecture over three centuries of social and economic change.

The buildings are arranged chronologically through the streets of the museum, creating a walkable architectural history of Danish urban life, with the oldest section depicting a 17th-century merchant town of half-timbered houses with thatched roofs and narrow cobblestone streets, and the early 1900s district presenting Neoclassical townhouses with gas street lamps, horse-drawn delivery vehicles and the sounds and smells of an industrialising city.

The working-class districts from the industrial period and the interwar years sit alongside middle-class residential areas, and the museum is fully immersive, with staff in period costumes demonstrating period crafts such as glassblowing, metalwork and bookbinding, and the smell of woodsmoke and the sound of hammering fill the streets throughout the day, creating a sensory experience that brings historical texts to life in a way that no written description can match.

The National Museum of Denmark oversees Den Gamle By, which operates as both an open-air museum and as a research centre for the history of Danish urban life, and the museum has been influential in shaping the open-air museum movement across Scandinavia and Central Europe since the early twentieth century, inspiring similar institutions in Sweden, Norway, Finland and Germany.

Beyond witnessing history, visitors experience the rich sensory contrasts of different eras—moving from the craft workshops with their smoke and hammering to the quiet of a 1920s middle-class apartment with its tiled stove and floral wallpaper, and then out onto cobblestone streets where bicycles are chained to posts and the modern city has grown around the museum since the 1970s, creating a jarring and fascinating juxtaposition of past and present.

The museum has expanded over the decades to include more periods and more stories, with the 1970s district added most recently, capturing the era of colour television and plastic furniture that Danes of a certain age will remember from their childhood, making the museum a place of personal nostalgia as well as historical education, and giving younger visitors a glimpse of a world their parents or grandparents grew up in. The combination of scholarly curation and genuine sensory richness makes Den Gamle By one of those rare museums where both academic historians and ordinary visitors leave feeling they have gained something irreplaceable, a lived sense of how ordinary Danes once lived, worked and raised families in cities that have since been transformed beyond recognition.

It is one of the oldest and most respected open-air museums in the world, set the template for similar museums across Scandinavia and Central Europe.

The chronological arrangement creates an unusually coherent sense of urban history unfolding over 300 years, making the passage of time tangible and personal.

The sensory richness—the smells, sounds and textures of different eras—makes historical empathy possible in a way that a conventional museum cannot achieve.
