The municipality of Wiesweiler celebrated its 675-year jubilee of first documentary mention in 2011, in line with information from writers Dolch and Greule holding that the village's first documentary mention was in a 1336 document, known from a 1440 copy, under the name "Winsewilre". Investigation has since uncovered an earlier mention, under the name "Wiswilre", as early as 1287 in a document from the Hornbach Monastery. This supposedly means that the municipality will be celebrating an 800-year jubilee of first documentary mention in 2087.
