These Photos Illustrate The Breakneck Speed Of Calgary Development


It's hard to believe the most of these photos are less than 100 years old.

It just goes to show how far Calgary has come in its short history and how quickly development has happened, starting in the downtown core and extending out.

Many of these photographs and postcards — all of which are part of the Calgary Public Library's "Postcards From The Past" digital archive — have been donated from the private collections of Calgarians and Albertans interested in preserving the history of Alberta's largest city.

We've made sure to keep the library's original descriptions and dates, where available.

Can you believe how much Calgary has changed?
