KOBLENZ | The Middle Rhine Museum or Mittelrhein-Museum at Forum Confluentes

After Bonn in 2023 and Münster in 2024, Dennis and I went further than North Rhine-Westphalia for our 2025 Christmas market in Germany outing. We went to Koblenz in Rhineland-Palatinate, at the confluence of the Rhine and the Moselle rivers. Hence the name of the city.

We love a good city (history) museum. We visited – amongst others – the Munich City Museum, the Kassel City Museum, and Berlin Global at the Humboldt Forum. All of them in Germany. And the Museum of Copenhagen is definitely located in København.

The Middle Rhine Museum or Mittelrhein-Museum is one of Germany’s oldest civic art museums and a central cultural institution of the City of Koblenz. Since 2013, it has been housed in the Forum Confluentes on Zentralplatz, Central Square, a purpose-built cultural complex that brought together major municipal cultural facilities at the heart of the city.

The move marked the end of a long history of temporary locations and represented a decisive step in securing the museum’s future, improving accessibility, and allowing a far broader presentation of its collections.

Origins and early development

The origins of the Middle Rhine Museum date back to 1835 and are closely linked to the private collection of the Neuendorf parish priest and educator Joseph Gregor Lang.

Lang, a cultivated and art-loving clergyman, assembled a significant collection of more than 200 paintings in the modest parish house of Neuendorf, now a district of Koblenz. Shortly before his death in 1834, he bequeathed this collection to his native city.

After Lang’s death, the City of Koblenz took over the collection and began exhibiting it publicly from 1835 onwards. Initially presented in the Free School for Boys in Kastorstraße, near the Bürgerhospital, the collection became known as the Municipal Lang Painting Collection. The first director was the Koblenz painter Johann Baptist Bachta, followed later by Daniel Dienz and Gottlieb Theophil Gassen.

From the outset, the museum’s history was characterised by frequent relocations. Between 1835 and the early 20th century, the collection was successively housed in rented rooms in the Casino Society building, the former town hall at Am Plan (On The Plan), the Grocers’ Guild House in Kornpfortstraße, the municipal department store on Florinsmarkt, the city theatre on Clemensplatz, and finally the Alte Burg (Old Castle). These moves reflected both the growing scope of the collection and the city’s ongoing struggle to provide suitable accommodation.

Expansion and institutional consolidation

By the late 19th century, the museum landscape in Koblenz had become more complex. In 1883, a museum association was founded, which began collecting archaeological material, applied arts, objects of cultural history and city views related to Koblenz and its surroundings. For a time, these collections coexisted alongside the Lang painting collection, though often in competition for space.

Around 1900, the painting collection moved into the Alte Burg, while the municipal department store on Florinsmarkt became home to other museum collections. The outbreak of World War I brought this arrangement to an abrupt end. Both museums on the Moselle riverbank had to give way to air-raid protection measures and food supply requirements. In the chaotic post-war years and following severe flood threats in 1920, the collections were dispersed across various municipal buildings.

A turning point came when unused rooms in the Electoral Palace or Kurfürstliches Schloss, not occupied by French occupation forces, were made available.

With the support of the city, the Prussian monument authorities and the occupying power, the collections were reunited there. For the first time, the museum had accommodation that was both representative and adequate, and its holdings grew substantially during this period.

The impact of war and post-war reconstruction

Civic donations played an important role in expanding the museum’s holdings, including a notable endowment from Thekla of Düsseldorf in 1917. In the 1920s, under director Adam Günther, the museum placed a stronger emphasis on archaeology. Shortly before the outbreak of World War II, the museum in the palace reached its greatest spatial extent.

During the war, however, the museum suffered significant losses. The National Socialist city administration prioritised large-scale propaganda exhibitions over the museum’s needs, and in 1944 parts of the collections housed on the ground floor of the palace were destroyed during Allied air raids.

Although many artworks had been evacuated in advance to Ehrenbreitstein Fortress and the Kemperhof bunker, the aftermath of the war proved disastrous.

Museum employee Alfred Kohlhoff, who had meticulously inventoried the collection, was forced to add numerous entries such as “taken by the Allies” or “stolen from the Ehrenbreitstein depot”.

Unlike the Wallraf-Richartz Museum in Cologne, which posted its own staff to guard its evacuated collections, Koblenz failed to take similar precautions. As a result, a large number of artworks were lost.

Temporary exhibition ‘Gestalten der Nacht’.

From Ehrenbreitstein to Florinsmarkt

From 1949 to 1965, the surviving collections were provisionally reopened to the public under the name Middle Rhine Museum in rooms at Ehrenbreitstein Fortress. In 1965, a more permanent solution was found when the museum moved into the reconstructed buildings of the Old Department Store on Florinsmarkt in the Old Town or Altstadt.

The museum remained there until 2013. Although this location offered a measure of stability after decades of moves, it soon proved inadequate. The buildings were not barrier-free, failed to meet modern fire safety standards, and offered insufficient space for exhibitions.

Only a small fraction of the museum’s holdings could be displayed at any one time. A comprehensive fire safety upgrade alone would have required several million euros, making a new solution increasingly unavoidable.

Zentralplatz and the creation of Forum Confluentes

The relocation of the Middle Rhine Museum is inseparable from the redevelopment of Zentralplatz. Unlike the historic squares of the Old Town, Zentralplatz was created after the Second World War during the reconstruction of Koblenz.

After the closure of a large department store in 1996, the area fell into decline, with vacant buildings and underused commercial spaces.

In 2001, the Rhineland-Palatinate Ministry of the Interior and for Sport proposed a comprehensive reorganisation of the square. The Koblenz city council designated Zentralplatz and its surroundings as a redevelopment area in 2003.

An architectural competition followed in 2007, won in 2008 by the Dutch firm Benthem Crouwel with a concept combining retail and culture under the name Forum Mittelrhein.

After intense public debate – often referred to as the ‘Zentralplatz battle‘ – the city council approved the project in 2009. Construction began in 2010, with the shopping centre Forum Mittelrhein opening in September 2012. Adjacent to it, the cultural building Forum Confluentes was completed and opened on 20 June 2013.

The Middle Rhine Museum at Forum Confluentes

The Forum Confluentes provided the Middle Rhine Museum with its first purpose-designed home. The five-storey cultural building stands at the northern end of Zentralplatz and forms part of a broader urban ensemble that includes a 6,000 m² open square with a green island and water feature.

Within the Forum Confluentes, approximately 3,200 m² are dedicated to the Middle Rhine Museum, including exhibition spaces and administration. The building also houses the Koblenz City Library, the city’s tourist information centre, and formerly the Romanticum, an interactive exhibition on the UNESCO World Heritage Site Upper Middle Rhine Valley, which closed in 2023.

The modern facilities resolved long-standing issues of accessibility, safety and presentation. Barrier-free access is provided throughout, and the museum can now display a significantly larger proportion of its holdings. In its first year at the new location, visitor numbers rose to around 24,000, three times as many as at the former Florinsmarkt site.

The collection

The core of the Middle Rhine Museum’s collection remains the Lang painting collection, which spans late medieval sacred art, Dutch masters of the 17th century, and painting of the 18th and early 19th centuries. Works by regional artists, notably Januarius Zick, form an important component, alongside a strong emphasis on Rhine Romanticism, with landscapes and city views of the Middle Rhine region.

Today, the museum encompasses more than 2,000 years of art and cultural history of the Rhineland. Its holdings include around 20,000 objects, among them more than 1,100 paintings, approximately 8,000 prints and drawings, over 300 sculptures, and extensive collections of applied arts, furniture, textiles, militaria, archaeological finds, architectural fragments, ceramics, coins and photographs.

In the field of contemporary art, the museum holds substantial groups of works by artists such as K. O. Götz and Heijo Hangen.

A particularly striking object on display is the original head of the Kaiser Wilhelm I Monument, underscoring the museum’s role not only as an art museum but also as a custodian of regional history.

Significance

As housed within the Forum Confluentes, the Middle Rhine Museum represents the culmination of nearly two centuries of civic commitment to art and culture in Koblenz. From its beginnings as the private passion of a single collector to its present role as a modern municipal museum, it reflects the cultural identity of the Middle Rhine region and the enduring engagement of the city’s citizens. The move to Forum Confluentes has ensured that this legacy is preserved, accessible and visible at the very centre of Koblenz’s urban life.

A visit

While the Middle Rhine Museum is presented as a civic or city museum, it’s mostly an art museum. That’s fine, but we expected a city history museum.

Noteworthy is the access card you get at the ticket office. It’s like an office badge. You can use it for the lockers and to enter. You return the card after the visit.

While we there, there was a temporary exhibition on the night, ‘Gestalten der Nacht‘.

We spend I think 1.5 hours at the museum.
