Kreuzlingen is a municipality in the district of Kreuzlingen in the canton of Thurgau in Switzerland. It is the seat of the district. It is the second largest city of the canton, after Frauenfeld with a population of over 17,000. In 1874, the municipality of Egelshofen was renamed Kreuzlingen. It reached its present size with the incorporation of Kurzrickenbach in 1927 and Emmishofen in 1928. It is located on Lake Constance where it narrows to form the Untersee, bordering with Konstanz in Germany. It is halfway between Schaffhausen and Rorschach on a slightly southward-dipping west-east axis.
Earlier, the majority of the inhabitants made a living in the wine industry. However, because of diseases and bad harvests, the last wine grapes were raised in Kreuzlingen in 1938. Today, the local economy is largely commercial and manufacturing, with the largest employer being a clothing manufacturer.
