Yes, this is a replica of St Peter's but it is beautiful and fascinating in it's own right.
When we entered we were offered a free guided tour by Michael, a local college student studying history. I am thrilled that we took him up on his offer! He had keys to several of the chapels and areas of the church that visitors can not access on their own and he was a wealth of knowledge!!! He was able to provide us with lots of information about the church as well as Montreal's rich religious history. This really enhanced our visit!!
