Zollstock is a district () located in Rodenkirchen, a borough () of Cologne west of the river Rhine. It borders the districts of Klettenberg and Sülz to the north west, Neustadt-Süd to the north, Raderberg and Raderthal to the east, and Rondorf to the south. Zollstock spans an area of 5.03 square kilometres. History 
Zollstock was first mentioned as a settlement in an 1877 address book. Increased construction in the area began in 1881 when a Neustadt district, an expansion of the original nucleus, was added to the city. Due to an abundance of local clay pits, Zollstock was initially dominated by brick manufactures. The district's name is derived from a local tollhouse () which stood at a crossing of dirt roads in what later became Zollstock. In 1896, the district was prepared for the construction of the Südfriedhof, a large monumental cemetery: existing roads were expanded and Zollstock was connected to the city's tram network. The cemetery opened in 1901 and remains one of the district's main sights. After the First World War, a number of residential neighbourhoods were erected in the district. Though this initially included mainly detached homes, blocks of flats increasingly became the norm from 1925 onwards. Since the 1980s, much of Zollstock's housing stock has been subject to modernisation and refurbishment. Demographics
