Next to the Serial Killers Museum in Florence, Italy, this one might be the most morbid we've come across. The intentions of the place are not to induce fear in squeamish types (although it's quite likely to do so), but rather to investigate human ritual by showcasing photographs of the deceased. MoMP is focused on photography as preservation of memory and features over 1,000 mourning photographs and negatives, some dating back to the mid-1800s. Currently, the collection can only be viewed by appointment; the museum encourages guests to schedule 2 to 3 weeks in advance. But if you don't feel like calling ahead and waiting to check out these morbidly fascinating shots, MoMP's website has about 10 percent of its collection available for online viewing and is in the process of transferring all mourning photos to its website.
