A statue of Plains of Abraham hero James Wolfe, originally mounted in New York and then in front of the Calgary Planetarium for a couple of decades has been placed in South Mount Royal Park near Wolfe and Montcalm streets. Not sure how old the statue is, but the artist died in 1936, so pretty old.
(Incidentally, I think South Mount Royal park was the last known location of the "Amazon Statue" that was originally in front of the Carnegie Library (Memorial Park Library).)
