There were two cemeteries in Oberkassel in the 19th century. There was a burial ground in the churchyard of the Catholic church of St. Cäcilia until the middle of the 19th century. To the south of the later Oberkassel town hall, the dignitaries of the Reformed Church were buried around the old Protestant chapel (1683) in the Protestant parish cemetery. The Oberkassel industrialist Gabriel Adrian had donated a small plot of land near his home as a cemetery for the Protestants. From 1855 to 1888, this was used as a burial ground, as there was a dispute between Catholics and Protestants over the burial of Protestants in the Catholic cemetery. Many Protestants worked in lignite and basalt mining, the concrete industry and the alum smelter in Oberkassel and the surrounding area. As the capacity of the Protestant parish cemetery was exhausted, the Protestant parish acquired the land on Langemarckstraße in 1888 for a new cemetery, which was elevated to the status of a parish cemetery in 1905. The denominational cemeteries were then closed.

The cemetery suffered severe damage during the Second World War and lost much of its original appearance. Oberkassel included various individual communities with Berghoven, Hosterbach, Römlinghoven, Ober- and Niederdollendorf and Heister- bacherrott. A municipal reorganization with various incorporations took place in 1969 and another in the 1980s. The Protestant cemetery at the chapel was not officially closed until 1983. A chapel dating from 1959 stands in the middle of the cemetery. The previous building was demolished and replaced by the simple architecture of the 1950s and 1960s.

There are some remarkable graves in the cemetery. The Adrian family has typically Protestant graves, which were relocated from the private Protestant cemetery. They are characterized by classicist forms and inscribed biblical quotations and are among the oldest graves in the cemetery. The graves of the Hüser and Kalkuhl/Heel families, on the other hand, are important contemporary documents. There are also less elaborately designed graves such as those of the Carstanjen and Hennicke families with lattice enclosures and pedestal stones.
