Montreal Things to Do: 1,065 reviews and 1,781 photos
Walking through the city we came to the old cathedral and became aware of the amazing engineering used during the construction of the underground city as it went directly under the cathedral.
The old cathedral weight of 8,200 tons had to be supported and stabilised for the duration of the work by the developer of the underground city.
The picture tells the story and to us it looked like the cathedral got by unscathed.
