Mülheim an der Ruhr is situated at an elevation of 40 m on the river Ruhr between the neighbouring cities Duisburg to the west, Oberhausen to the north, Essen to the east and Ratingen to the south. The city of Mülheim has a population of about 170,900 (2016).

Mulinhem was first mentioned in a written document dating from 1093. However, Broich castle, on the left side of the river was probably already founded in 883/884. In 1372, after the death of the last lord of Broich, the domains came in possession of the counts of Isenberg-Limburg. At the beginning of the 14th century, the domains were partitioned into Limburg-Broich and Limburg-Styrum (both today parts of Mülheim). In 1508/1511 Limburg-Broich was inherited by the counts Daun-Falkenstein, while Limburg-Styrum later obtained the status of a territory immediate to the empire (until 1806). During the course of the 17th and 18th centuries, the Duchy of Berg successfully claimed the sovereignty over the area. With the death in 1682 of the last count of Daun-Falkenstein during the Eighty Years' War, the domains fell to the counts (1779 princes) of Leiningen. The industrialisation of Mülheim began around 1770 when the river Ruhr was expanded to a waterway. Coal trading became important after 1780 when a river lock at Mülheim had made it possible to navigate the upper part of the river. Two years after the foundation of the French Grand Duchy of Berg, Mülheim was declared a muncipality. Together with the entire grand duchy, Mülheim became part of Prussia following the Congress of Vienna (1815). In 1846, Mülheim obtained the status of a town by Prussian law. Between 1850 and 1890 the city developed from being a shipping town into an industrial town. Steel production using coking coal began in 1849, the first briquette factory opened in 1861. Coal mining within Mülheim, however, later proved not being as productive as ogther large mines in the Ruhr area. The town was connected to the Berg and Mark Railroad in 1862 and to the Ruhr Valley Railroad in 1872–1882. August Thyssen founded his later famous steel company in 1871. Mülheim became the cengre of a district in 1873 (the western part of which was separated in 1887 as district Ruhrort). In 1904, Mülheim became a city independent of the district. During World War II, about 65% of the city was destroyed by Allied bomb raids. The second half of the 20th century brought a serious change in the econommic life. The last steel factory closed in 1964, and two years later coal mining also was terminated.

The picture on glass no. 3368 shows a view of Kahlenberg (90 m) on the right side of the Ruhr river. The southern part of the hill was edveloped as a recreation area between 1879 and 1913.

Another glass in this collection is a souvenir from Mülheim am Rhein, a city district of Cologne.
