The Ruhr: A Region Reinvents Itself, One Factory at a Time

A Trail Through Coal and Steel

Since 1999, the Regionalverband Ruhr, the region's municipal planning and development association, has brought together the area's most important historical sites under the Industrial Heritage Trail. It now comprises 57 main sites, including 27 anchor points, 17 viewpoints and 13 historic workers' settlements, alongside more than 1,000 further locations spread across 32 themed routes. Where coal was once mined, coke burned, iron smelted or energy distributed, visitors can now join guided tours, browse exhibitions and attend events.

New uses range from museums and concert venues to hotels, restaurants, sports facilities, parks and artists' studios, alongside technical facilities that still serve their original purpose.

The best-known example is the Zollverein Coal Mine in Essen, which closed in 1986. Together with its coking plant, it has been part of the UNESCO World Heritage List since 2001. Where coal was once processed, the site today houses the Ruhr Museum, the Red Dot Design Museum and facilities for art, design and events, among other attractions.

Engineering on Display

Other sites show just how far this kind of repurposing can go. The Zollern Colliery in Dortmund was built between 1898 and 1904 as a showcase mine, intended to represent the industry at its most modern. Its machine hall, built of steel and glass beneath an ornate Art Nouveau portal, remains the site's best-known feature. Today it operates as a museum of industrial culture, where visitors can examine original machinery and hoisting equipment and descend into a re-created underground gallery.

The Henrichenburg Boat Lift in Waltrop tells a different story: no raw materials were ever extracted here. Opened in 1899, it lifted ships on the Dortmund-Ems Canal over a height difference of around 14 m, and performed this task for more than 60 years. It too now operates as a museum, tracing the history of canals, inland shipping and ship technology. Visitors can tour the historic facility and take boat trips.

Light, Art and Power: Reworking the Ruins

In Mülheim an der Ruhr, an old railway water tower has become a camera obscura. The tower's three levels house a museum devoted to the prehistory of film, with more than 1,100 exhibits. High in the former water tank above, an optical installation projects a 360-degree image of the surrounding cityscape, making it, according to the museum, the largest walk-in camera obscura in the world.

Even further removed from its original use is the former blower hall of Dortmund's Phoenix West blast furnace works. Machines here once generated the blast air that fed the furnaces, until the hall was decommissioned in 1998. Since 2023, it has housed Phoenix des Lumières, where paintings and other artworks are projected across its walls and floors, turned into moving images and soundscapes over 5,600 sq m of surface. Part of the steelworks has become a digital art center.

The Recklinghausen substation offers an unusual combination of old and new uses. It is both a protected historical and technical monument and an active part of the region's power supply. The buildings no longer needed for day-to-day operations now house Zeitreise Strom, the German Museum of Electricity, which traces the history of electrification across roughly 2,500 sq m. The substation's actual equipment, meanwhile, was modernized in the 1990s and remains in operation.

Other major sites belonging to the region's industrial heritage include the Oberhausen Gasometer, a former gas holder, the Jahrhunderthalle in Bochum, the Hansa Coking Plant in Dortmund and Landschaftspark Duisburg-Nord. At the former Thyssen ironworks, visitors today can climb a blast furnace, scramble through ore bunkers and dive in an old gasometer. The production facilities form a 180-hectare landscape park.

The Business of Nostalgia

This repurposing is about more than preserving heritage. It forms part of a tourism and leisure economy that now generates considerable revenue.

Gross tourism revenue in the Ruhr region was estimated at €8.01bn ($9.31bn) for 2024, a figure that covers not just hotels but smaller accommodations, day trips and tourism-related spending more broadly. The wider economic sector of leisure and events employed 87,496 people subject to social security contributions in 2025, a slight decline of 0.2% on the previous year, even as its roughly 20,200 companies generated revenue of €14.97bn ($17.40bn) in 2024.

Within that sector, the smaller submarket of events, leisure, sport and tourism accounted for €5.52bn ($6.42bn) in revenue, a figure that reaches well beyond the repurposed industrial sites alone. Even so, the numbers confirm that leisure, culture and tourism have become a measurable economic sector for the region in their own right.

Where Industry Still Runs

Despite mine closures and the rise of industrial heritage tourism, the Ruhr region remains a significant industrial location. The sector that the regional economic development agency Business Metropole Ruhr defines as industrial core and business services still employed 321,838 people in 2025, even as both revenue and employment declined: its 19,304 companies generated €74.24bn ($86.27bn) in 2024, down 4.9% on the previous year, while employment fell by 2.3%.

The juxtaposition of industrial history and active industry is especially visible in Duisburg. Visitors walk through a blast furnace works shut down in 1985 at Landschaftspark Duisburg-Nord, while just a few kilometers away, Thyssenkrupp Steel continues to produce steel.

Yet even this remaining industrial core is changing. Thyssenkrupp Steel has concluded a restructuring agreement with the country's largest industrial trade union running until 2030, under which Germany's largest steelmaker plans to cut production capacity to between 8.7 and 9 million tons and cut or outsource around 11,000 jobs. At the same time, it is investing in a new direct reduction plant to produce steel with lower carbon dioxide emissions.

A Region of Two Economies

The labor market tells a different story, one in which tourism and education alone cannot make up for the region's lost industrial weight. In August 2026, 273,045 people were unemployed in the Ruhr region, an unemployment rate of 10.8%, well above both the state figure of 8.0% and the national rate of 6.5%.

Municipal budgets remain similarly strained: the cities and districts of the Ruhr region closed 2024 with a deficit of €1.38bn ($1.60bn). Yet the municipal fiscal crisis is no longer a problem exclusive to the region.

Two economic landscapes now sit side by side. In one, steel, machinery and industrial intermediate products continue to be manufactured. In the other, cycle paths run along former railway lines, visitors climb blast furnaces, art is projected in old factory halls, and museums explain the technology that once made the region great.

The old industry has taken on a second economic function. Its buildings now draw visitors and generate revenue in leisure, culture, gastronomy and tourism, even as industry and industry-related services continue to employ more than 320,000 people and generate many times the revenue that tourism does. Where things were once produced, the production of the past is now on display in many places. In the Ruhr region, structural change is not just a statistic. It can be cycled through, walked into and climbed.
