The Zeche Zollern (colliery) is located in the northwestern suburb of Bövinghausen of Dortmund, Germany.
Construction began in 1898, completed in 1904.
It connected 2 shaft minings underground, Kirchlinde and Bövinghausen.
Thousands of people worked there underground between 1899 and 1955 and lost their health for earning little money to take care of their families. Since 1960 the Zeche Zollern is an important point of the European Route of Industrial Heritage.
If you are interested, I´d like to invite you to follow me some steps through the past.
