The story of Iserlohn
Iserlohn, known as the "Forest City," offers a distinctive blend of natural beauty, historical depth, and industrial heritage within Germany's Sauerland region. This city, the largest in the Märkischer Kreis district, provides a serene escape amidst verdant forests, rolling hills, and tranquil lakes, alongside a tangible connection to its past.
From exploring remarkable dripstone caves to wandering through engaging historic streets, Iserlohn presents a varied array of experiences. Its identity is deeply intertwined with both its natural surroundings—reflected in its name, which literally means "iron forest"—and its long-standing industrial traditions, particularly in metalworking. Whether you seek outdoor adventures or a journey through time, Iserlohn invites you to uncover its many facets.
## From Medieval Craft to Industrial Powerhouse Iserlohn's origins trace back to the 11th century, with the first written mention of "Lon" appearing around 1150. It was officially granted municipal rights in 1237 by the Count of the Mark. During the Middle Ages, Iserlohn established itself as a significant center for the production of armaments and light metalware.
## Challenges and Rebellions The city faced numerous challenges throughout its history. In 1712, a devastating fire swept through Iserlohn. Later, in 1849, the city was the scene of a rebellion, reflecting periods of social and political unrest.
## Industrial Revolution and World Wars The 19th century saw Iserlohn's industrial prominence grow, particularly in needle manufacturing, a complex process involving over a hundred steps. This industrial prowess, especially in metalworking, made Iserlohn a target during World War II, as it produced war-relevant products like brass components and hardware for grenades. The city endured Allied bombing, leading to the construction of an air-raid shelter beneath the Oberste Stadtkirche. The war also brought immense tragedy to Iserlohn's Jewish community, with the destruction of its synagogue in 1938 and subsequent deportations.
## Modern Iserlohn In 1975, Iserlohn expanded significantly, incorporating surrounding municipalities like Letmathe, Hennen, Sümmern, and Kesbern, becoming part of the Märkischer Kreis district. Today, Iserlohn continues its industrial legacy with manufactures including machinery, pharmaceuticals, synthetic fibers, textiles, and metal products. It also serves as a center for the training of Germany's military pilots.
Begin your exploration at the Dechenhöhle (Dechen Cave), one of Germany's most visited show caves, discovered by railway workers in 1868. Marvel at the intricate stalactite and stalagmite formations during a guided tour. Adjacent to the cave is the German Cave Museum, offering insights into geology and the cave's discovery.
For sweeping views, ascend the Danzturm, a historic observation tower that offers vistas over Iserlohn and the surrounding Sauerland region. The tower, once a semaphore station, also has a restaurant at its base.
Delve into Iserlohn's industrial past at the Historische Fabrikanlage Maste-Barendorf. This 19th-century industrial settlement now functions as an artist and museum village, featuring a Needle Museum and displays on brass foundry. You can also visit the Stadtmuseum Iserlohn to learn more about local history, crafts, and industrial heritage.
Stroll through Iserlohn Old Town with its compact historic center, cafés, boutiques, and traditional architecture. Don't miss the Oberste Stadtkirche, a Gothic church dating from the 14th century, and the St. Pankratius Church (Bauernkirche), the oldest building in the city, believed to have been founded around 985 AD.
For outdoor relaxation, the Seilersee is a popular lake for walks, jogging, and boating during the summer months.
The best time to visit Iserlohn for general outdoor tourist activities is from late June to late August, with a peak in the first week of August, when temperatures are comfortable and skies are clearer.

For those who prefer fewer crowds, the milder spring (April to June) or fall (September to October) offer pleasant weather for exploring. Winter, from November to March, is colder and cloudier, but December brings festive Christmas markets.
