Mulheim

Foundation and First Mentions

The history of Mülheim is rooted in the early Middle Ages. The first documentary mention of a settlement named Mulinhem dates back to 1093. The city's name speaks for itself and translates as "Home of Mills," reflecting the original character of the location.

However, the actual settlement of the territory began much earlier. A major milestone was the construction of Broich Castle (Schloss Broich) at the end of the 9th century. This fortification, built to protect the region, became the core around which the settlement gradually formed, eventually growing into the modern city.

Key Factors of Formation

The development of Mülheim was determined by a fortunate combination of geographical and economic circumstances:

• Geography and Water Resources: Its location on the Ruhr River and the presence of numerous streams flowing into it created ideal conditions for building water mills, which gave the city its name and initial economic base.
• Trade Routes: Proximity to the historic Hellweg trade route facilitated the development of trade and the exchange of goods with neighboring regions.
• Political Center: Broich Castle served not only as a defensive structure but also as the administrative center of the Lordship of Broich, providing governance for the territory for many centuries.

Early Cultural and Economic Features

In its early period, Mülheim's economy depended entirely on water power. Mills were used not only for grinding grain but also for producing oil and paper, as well as for wood processing. This made the settlement an important craft center for the region long before the start of large-scale industrialization.

Cultural life traditionally centered around the castle and church parishes. Thanks to the development of shipping on the Ruhr River, Mülheim early on became a significant transport hub through which various goods passed, contributing to the growth of local merchant wealth and the expansion of cultural ties.

Chronology of City Development

The history of Mülheim an der Ruhr is a journey from a medieval settlement by a castle to an industrial giant and a modern green city. Below are the key milestones of this development.

• 883–884 — Construction of Broich Castle, which is considered the oldest preserved Carolingian fortification north of the Alps.
• 1093 — First documentary mention of the settlement named Mulinhem in the charters of Werden Abbey.
• 1808 — Mülheim officially receives city status and municipal rights, giving a boost to administrative development.
• 1839 — Opening of the railway line connecting the city with coal deposits and accelerating industrial growth.
• 1871 — Industrialist August Thyssen founds the company Thyssen & Co., turning the city into one of the centers of German metallurgy.
• 1901 — Mülheim receives the status of an independent city district (kreisfreie Stadt), separating from the rural district.
• 1912 — Opening of the Coal Research Institute (now the Max Planck Institute), which became a world center for chemical science.
• 1925 — Scientists Franz Fischer and Hans Tropsch develop the famous liquid fuel synthesis process at the local institute.
• 1966 — The closing of the last mine, "Rosenblumendelle," makes Mülheim the first city in the Ruhr region to completely stop coal mining.
• 1992 — Hosting the State Garden Show (MüGa), which transformed former industrial wastelands into a popular landscape park.

Stages of Transformation: From Port to Garden City

The development of Mülheim is a story of constant adaptation. The city has evolved from an important transport hub to an industrial giant, and then successfully reinvented itself as a center for science and green urbanism. Here are the key stages that defined the modern face of the city:

• The heyday of Ruhr shipping. In the 18th and 19th centuries, the Ruhr River became the main transport artery for coal transportation. Mülheim turned into a key transshipment point, leading to the formation of a powerful merchant class and the initial accumulation of capital for future industrialization.
• The era of industrialization and the Thyssen dynasty. The arrival of August Thyssen in 1871 changed the scale of the city forever. The founding of steel mills and machine-building enterprises triggered explosive population growth and an urban planning boom, turning a quiet town into a major industrial center.
• Becoming a scientific center. The opening of the Coal Research Institute (now the Max Planck Institute) in 1912 added an intellectual dimension to the city. Nobel laureates worked here, and it was here that discoveries were made that influenced the global chemical industry, cementing Mülheim's status as a city of science.
• The first coal-free city. In 1966, Mülheim became the first city in the Ruhr region to completely stop coal mining. This event marked the beginning of a large-scale structural restructuring of the economy, oriented toward the transition from heavy industry to the service and trade sectors earlier than its neighbors.
• Opening of the Rhein-Ruhr-Zentrum (RRZ). One of Germany's first indoor shopping malls opened here in 1973. This event marked the city's transformation into an important point on the region's retail map, attracting shoppers from across North Rhine-Westphalia.
• "City by the River" urban renovation. Hosting the State Garden Show (MüGa) in 1992 was a turning point in urban development. Abandoned industrial zones along the river were reclaimed and turned into extensive parks, returning riverfront access to residents and securing Mülheim's reputation as the "green lung" of the Ruhr region.

Architectural Identity: From Fortress Walls to "Ruhrbania"

The architecture of Mülheim an der Ruhr is a unique chronicle where pages of medieval history sit alongside monuments of industrial power and modern urban solutions. The city is not frozen in a single era but demonstrates a dynamic evolution of urban planning.

Historical Heritage: Romanesque, Gothic, and Baroque

The city's oldest buildings are linked to its defensive and religious functions. They form the historical core and atmosphere of Old Mülheim, recalling a time when the Ruhr was an important trade artery rather than an industrial zone.

• Carolingian Architecture and Classicism: Broich Castle is a unique monument whose oldest parts date back to the Carolingian era (9th century). Later, during the Baroque and Classical periods, the castle was rebuilt into a noble residence, but it retained its powerful fortress walls.
• Romanesque and Gothic: Saarn Abbey (Kloster Saarn) demonstrates a harmonious transition from Romanesque to Gothic style. Founded in the 13th century, the complex has preserved its medieval layout, supplemented by later elements.
• Church Architecture: St. Peter's Church (Petrikirche) on the church hill is an example of a Gothic hall church that has dominated the old town's skyline for centuries.

The Era of Industrialization and Art Nouveau

Mülheim's transformation into an industrial center in the 19th and early 20th centuries radically changed its appearance. This period saw the formation of the so-called "villa belt" and the construction of monumental public buildings reflecting the city's wealth.

• Gründerzeit and Historicism: The period of economic boom left the city a rich legacy of industrialist mansions (such as the Thyssen family villas). Mülheim City Hall (Rathaus), built in 1915, combines elements of Historicism with the monumentality characteristic of administrative buildings of the German Empire.
• Brick Expressionism: A prominent representative of 1920s architecture is the Stadthalle (Stadthalle). Located on the banks of the Ruhr, this building is considered one of the most important monuments of theater architecture from the Weimar Republic, standing out with its strict geometric shapes and the use of dark brick.

Modern Urban Planning and Postmodernism

In the second half of the 20th and early 21st centuries, the city reimagined its interaction with the river, moving from industrial use of the embankments to recreational and residential purposes.

• Functionalism and Reconstruction: Post-war restoration brought simple forms and functional buildings characteristic of the 1950s and 60s to the city, including the "Forum" high-rise.
• New Urbanism: The Ruhrbania project has become a symbol of the modern stage of development. This is a large-scale renovation of the embankment designed to turn the city center to face the river. The project includes the creation of new residential quarters, promenades, and a city harbor, harmoniously integrated into the existing landscape and connecting the historic center with the water.
