TUNNELS OF MOOSE JAW, CANADA
A huge labyrinth of underground tunnels was built beneath Moose Jaw in Saskatchewan back in 1908, and while this large network was originally constructed as a steam system, its purpose quickly transformed into something else. During the Yellow Terror, Chinese railway workers used to hide there with their families and, as the community grew bigger, the tunnels became a hub for all sorts of illegal activities. It was a time of Prohibition in the US and the underground was a perfect place for warehousing alcohol, as well as for prostitution and gambling. Even Al Capone’s presence there has been documented by different people and confirmed by his grandniece. Today, the tunnels of Moose Jaw are a tourist attraction and one of the best examples of a secret city beneath the city.
