There are certain parts of history that are ugly, full of horrific and shameful events that many would like to forget. But these dark times are part of our collective history — and present — and it’s important to acknowledge and learn from them so that we can make amends, move forward, and not repeat the same mistakes. In Portland, Oregon, there is a place that’s left a dark mark on the city, an underworld that was home to some truly horrific happenings in the 19th-century. Today, the Portland Shanghai Tunnel is not only a place of immense significance in Oregon history, but it’s also considered to be one of the most haunted places in the world.
