Waldsee ("Lake of the Woods") is the German immersion program offered by Concordia Language Villages. Located near Bemidji, Minnesota, Waldsee is also the site of North America's first certified passive house, which uses 85% less energy than a house built to the Minnesota Energy Code.
Waldsee is America's oldest and largest immersion program for German language and culture. Over 1,550 young people participate yearly, coming together from all 50 of the United States and many foreign countries. In 2009 Waldsee was recognized as a U.S. National Center of Excellence for its cultural immersion program by the American Association of Teachers of German.
Waldsee was the brainchild of professors Gerald Haukebo and Erhard Friedrichsmeyer at Concordia College in Moorhead, Minnesota, USA. In 1961, the first two-week session of "Camp Waldsee" was held for 72 villagers. The tuition was $75 and Erhard Friedrichsmeyer served as the dean of the program. Over the next decade, Waldsee began to grow in both the number of villagers attending as well as the number of weeks that the camp ran each summer. Waldsee's first "adventure program," Alpenland, was held at the Rising Wolf Ranch in Montana, where villagers learned German while enjoying hikes in the mountains and horseback riding.
In 1970, the high school credit program was launched, providing a four-week intensive instruction for high-school students equivalent to a full year's instruction in a traditional classroom. In 1973, Waldsee launched its first study abroad program, offering backpacking and biking trips to Germany, Austria, and Switzerland.
