At the northern end of the street sits the beautiful, historic chapel of the Hôtel-Dieu Hospital. It almost seems like a utopian oasis quaintly tucked into an urban environment. However, a paranormal mystery has long-plagued this exquisite street. Since the summer of 1929, mysterious knots have been appearing in one of the homes, tying up curtains and bedsheets and the like. According to various reports, some residents blame the unsolved mystery on a poltergeist.
