Benjamin Bathurst was a British diplomat who disappeared without a trace in Germany in 1809. In a day and age when sophisticated forensics didn't exist, this might not sound too mysterious - especially during the Napoleonic Wars when murders, robberies and assassinations were common.

Overtoun Bridge in West Dunbartonshire, Scotland was built in 1895 for ease of access to Overtoun house. While it is quite a nice looking bridge, it isn't anything special compared to most historical sites in Scotland... except for the fact that dogs crossing the bridge feel compelled to throw themselves to their inevitable demise.

This phenomenon has been occurring since the 1950s, with the bridge claiming the lives of dogs at an average rate of one per year.

While the tale of the Mary Celeste is one of the most enduring stories of missing ship crews, the Patanela is Australia’s very own maritime mystery.
