The inhabitants are called Kaysersbergeois. The name means Emperor's Mountain in German.
The high fortress that dominates the city serves as a reminder of both its strategic importance and its warlike past. Together with the rest of Alsace-Lorraine, Kaysersberg was annexed by Germany during a period of 48 years, between the Franco-Prussian War and the First World War.
Kaysersberg is one of the finest wine growing areas in Alsace. The first vines were brought here in the 16th century from Hungary, and wine production is still an important aspect of the town's economy today. Wine produced from the pinot gris variety is a local specialty.
Kaysersberg lies northwest of Colmar, on the eastern slopes of the Vosges mountains.
Kaisersberg was the birthplace of Albert Schweitzer (1875–1965), theologian, musician, philosopher, and physician.
