Bad Sassendorf: A Historic Spa Destination in Germany’s Heartland
Bad Sassendorf, 9 January 2026 – Nestled in the Soest district of North Rhine-Westphalia, Bad Sassendorf is a charming municipality renowned for its rich history tied to salt production and its status as a health resort. With a population of around 12,000, the town offers a blend of wellness, culture, and outdoor activities, making it an ideal spot for relaxation and exploration.
History and Geography
Bad Sassendorf’s roots trace back to the 8th century under the Merovingian dynasty, with evidence of Saxon settlements. The name “Sassendorf” reflects its origins as a Saxon village. Salt springs were documented as early as the 10th century, noted by the ambassador of the Caliphate of Cordoba in 973. The town was under the Archbishopric of Cologne from the 12th century, and salt exploitation was a right of free peasant families.
From the 19th century, brine was used for bathing and medicinal purposes, leading to the opening of the first spa in 1852. Commercial salt production declined and ceased by 1952. The village was officially renamed Bad Sassendorf in 1906. During the Second World War, from February 1944 to April 1945, inmates from the Neuengamme concentration camp repaired railway tracks here.
