Worthwhile: The Westphalian salt route
Salt production and salt trade have played a role in the Hellwegbörde (Westphalia) since time immemorial. The first salt mines already existed in the Iron Age more than 5000 years ago. The Westphalian salt route from Unna to Salzkotten, along the old Hellweg trade route, follows the traces of this history.
There are many things to discover along the approximately 90 kilometre route: churches and chapels, such as the pilgrimage basilica in Werl - the third largest pilgrimage site in Germany. Graduation houses, such as the 120-metre long and 12.5-metre high Graduation House I in Bad Westernkoten. Or the adventure museum "Westphalian salt worlds" in Bad Sassendorf.
