Original Centre Street Bridge Lion Project
Background
The original Centre Street Bridge lions, created by James Thomson, were fashioned in the likeness of the bronze lions at the base of the Nelson monument in London's Trafalgar Square. Over the years, the lions grew to be well-known symbols of Calgary's strength, integrity and independent character.
Conservation
The lion from the northeast side of the Centre Street Bridge was taken in for repairs and conservation. The preserved lion is now displayed in Rotary Park, on the bluff overlooking Centre Street Bridge. From this location, Calgarians can view the original preserved lion in the park and the recast replacement lions on the bridge.
Arrested decay conservation approach
The original lion sculpture from the Centre Street bridge has been conserved to remain in a state of "arrested decay". This means the lion is displayed to show its age and history through preserving the visual indicators of wear such as cracks and weathering from exposure to the elements.
New Location
Rotary Park, the home of one of the original Centre Street Bridge lions, offers Calgarians a chance to experience this century-old sculpture in a fresh, accessible setting. Its placement highlights the connection between Calgary’s past, present and future, as the preserved lion now overlooks the recast versions on the bridge below. Visiting Rotary Park allows you to appreciate a significant piece of the city’s history — while also seeing where it once stood and what now stands in its place.
Engagement
In 2013 Council asked that the original Centre Street Bridge lions be part of the West LRT public art process. After public consultation, the community engagement on this idea, there was a lack of strong public support for incorporating the lions into the West LRT and Rotary Park was chosen as the new location.
