Twitter/@cityofcalgary Calgary mayor Naheed Nenshi poses with the 110-year-old time capsule retrieved from City Hall on Nov. 8, 2018

More than a century ago, members of Calgary's city council gathered items important to the city at the time and sealed them in a copper box, placing the box within a cornerstone of City Hall.

Today, mayor Naheed Nenshi pulled that box out, revealing a snapshot of a small city just beginning to grow.

The capsule was put in place on Sept. 15, 1908, by then-mayor Arthur L. Cameron. At the time, Calgary's population was only 12,000 people, and the province's vast oil resource had yet to be discovered.
