Either of the links will take you to more information and entries from the museum. Definitely worth looking at.
The Museum of Broken Relationships grew from a traveling exhibition revolving around the concept of failed relationships and their ruins. Unlike ‘destructive’ self-help instructions for recovery from failed loves, the Museum offers a chance to overcome an emotional collapse through creation: by contributing to the Museum’s collection.
Every exhibit is composed of an object, its title, basic details about location and duration of the relationship and a personal story as submitted by its donor.
