What looks like a chapel (left side of the postcard) near the big corner guest house ‘Zum Bären’ used to be a ballroom in its very beginning. Then it became a movie theater (1913), which in turn became the infamous disco ‘La Soirée’ in later years (1975 – 1991).

This black and white photo was taken by a U.S. soldier back in 1962.
This is awesome Maria! I was stationed at Camp King from 1984 – 1986. Very good times and memories. Hope you are doing well.
Fred, thanks so much for your additional contribution!
Both my sister and I went to La Soirée back in the 80’s. We lived in Friedrichsdorf with our parents. I remember my teen years fondly having worked summer hire at Camp King. Why “infamous “ La Soirée?
The infamous part about La Soirée is just hearsay :-). Most people remember it very fondly for they fun they had, the silly things they did, and some lasting romances.
