The tradition of putting a crown on a beautiful young woman and sending her out to promote the local wine or asparagus crops dates back many years in Germany. But it's only been since 2001 that a weekend has been set aside to honor all of the country's diverse queens.

The so-called "Königinnentag," or Queen Day, has been held every three years since then. This year, it's taking place from August 19-21 in the town of Blomberg, North Rhine-Westphalia.

Held mid-harvest season, some 200 queens from all of Germany's 16 states are expected to attend the event where they can share their experiences, participate in a parade and give autographs.
