Haunted Montreal Blog #90 – City of Montreal Archives
A massive vault sits below Montreal's City Hall and some historians say it is haunted. The sealed chamber is located under the front of City Hall, between its foundations, the sidewalks of Gosford and Notre-Dame streets and the eastern side of Place Vauquelin. The eastern portion of the vault was constructed from 1919-1921 and the western part in 1952. Its purpose is to house and protect the valuable Archives of the metropolis.
