This network of tunnels below downtown Portland may or may not have been used for the process of "Shanghai-ing," the unseemly practice of capturing able-bodied men and selling them for labor.

Whatever the true history, it's fun to take a tour and form your own spooky speculations.

Though it's facade might not look frightful, this mansion has a strange past. It was built by a widow named Sarah Winchester, the heiress to the famous rifle company. According to the house's web site, following the untimely deaths of her daughter and husband, a psychic told Winchester that the tragedies had been caused by the spirits of those killed by the family's guns. She was told to build a large home for the ghosts to ensure her safety, with one stipulation: Construction could never stop.

The photo of you lying down beneath the last step is, of course, optional.
