Bendisberg Visitor Mine
Not far from Langenfeld, in the district of St. Jost, is the Grube Bendisberg visitor mine. Guided tours can be arranged here to descend into the interior of the Eifel. Here you can get an insight into the daily work of the miners, who have been mining ores here for decades. Due to the size of the mine, different guided tours can be offered, which allow some exciting hours. Apart from the regular guided tours on the weekend, there is the possibility to book other guided tours from Tuesday to Friday after registration.
Furthermore, the pilgrimage chapel in St. Jost with its baroque altar is a jewel worth seeing.
