At the Zollverein Coking Plant, once the largest central coking plant in Europe, the second stage of the Path of Coal starts. Between 1961 and 1993, up to 8,000 tonnes of coke were produced here every day.
The Path of Coal
Up to 1,000 coke workers worked in three shifts around the clock. Today, visitors get an insight into coke production on the “black side” with the ovens and machines.

On the rooftop of the mixing plant
The coal from the colliery arrived at the mixing plant. On the rooftop, visitors can experience an impressive view of the entire plant during a guided tour of Zollverein.
And that’s the view.
Mixing Plant, Bunker Level
Inside the mixing plant, the different types of coking coal supplied by the Zollverein Coal Mine and other mines were blended together. Each type of coal was first stored temporarily in one of the twelve large bunkers...

... and then fell through the hoppers directly onto conveyor belts, which transported the coal mixture to the coal towers.

From the coal towers, the well-mixed coking coal was loaded onto the charging car, which filled the coke ovens from the top.

The Coke Ovens
Visitors in the hot alley directly in front of the coke ovens. A single oven is 6 metres high, 13 metres deep but only 45 centimetres wide.

One oven could hold up to 28 tonnes of coking coal, which was then baked into coke for 16 to 18 hours at temperatures of around 1.000 degrees Celsius in the absence of air.

In addition to enormous installations and lofty heights, a guided tour of the coking plant also offers a detour into the “underworld” of the plant. Here you can see the former flue leading to the chimney.
The White Side
Many kilometres of pipelines shape the appearance of the white side of the coking plant. They were used to extract the raw gas from the coke ovens. After cleaning and separating by-products such as sulphuric acid, tar, ammonia and benzene, a large part of the gas was returned to the coke ovens to fuel them. Excess gas was fed into the municipal gas grid.
Experience the Coking Plant
At the coking plant, too, guests are offered further support in understanding the plant and its processes in addition to the personal contact with the guides: below the quenching tower where the quenching cars once pulled the red-hot coke under a 40.000-litre water shower is the first information point of the new Zollverein Coking Plant Monument Path.
Powerful Visual Staging
Inside the building, visitors gain a different insight into the coking plant and enter a world that was characterised by heat, steam, complex technical processes and, above all, hard work around the clock.

The functions of the huge machines and the activities of the coke oven workers become visible and comprehensible at this over seven-metre-long model of the black side. The highlight: individual segments can be pulled out.
Touch and participate
The third facility on the Zollverein UNESCO World Heritage Site that has been preserved in its original state is dedicated to children and families.
Since 2020, the shaft area and the mine car circuit of Zollverein Shaft 1/2/8 have been the Zollverein Interactive Colliery. Children, young people and families can actively experience what working at the coal mine was like.
In this section of the Monument Path, the emphasis is on hands-on activities. Equipped with pit jackets, helmets and gloves, the children set off on an exciting journey through the coal mine. They can also get actively involved at the various stations.

Out-of-school place of learning with a fun factor
During the summer and autumn holidays in North Rhine-Westphalia, a special holiday programme is offered for schoolchildren. They not only become miners but also researchers and find out why the miners washed the coal and which cake was baked in the “biggest toaster” in the world.

Values, Tradition and Teamwork
The workshops not only impart knowledge about the function and tasks of the machines and miners. Children and young people also learn a lot about the values that are so important for mining, such as teamwork and cohesion.
Fun, puzzles, action, moving around and lots of fresh air: the Zollverein site offers plenty of space for exploration in the outdoor areas. Adults, families, children and young people can playfully explore the 100 hectares of the UNESCO World Heritage Site with their smartphones.
In order to reach as many interested visitors as possible, Zollverein offers guided tours for guests with visual or hearing impairments. People with impaired vision can experience how coal was mined and processed at Zollverein at touch and sound stations. Guests with impaired hearing can either take part in a guided tour with a hearing amplifier or a guided tour in sign language, as required.
