This presentation is part of Are We There Yet? Preservation of Roadside Architecture & Attractions Symposium, Tulsa, Oklahoma, April 10-12, 2018.

By Kelly Caldwell, Sophia Zweifel, Joseph Sembrat, and Mark Rabinowitz


The Centre Street Bridge Lions (1916) and Dinny the Dinosaur (1934) along with the Maurice Savoie Mural (1966) are three examples of large-scale outdoor artworks that adorn the roadways and buildings of Canada, each with their own unique history and setting. These sculptures represent an evolution in style of Canadian outdoor attractions spanning over 50 years. Though these sculptures are not directly on the historic Trans-Canada Highway, they span the breadth of Canada geographically, from the Atlantic to the Rockies. These large-scale artworks act not only as historic works, but serve as intrinsic memories for locals and visitors, especially ‘Dinny’; a favourite of travelers to Calgary since the 1930s.

In 2017, Conservation Solutions (CSI) completed a range of assessments and treatments for the Calgary, Alberta – City Hall Lions and the Maurice Savoie Mural in St. John’s, Newfoundland, and are scheduled to begin work on Dinny the Dinosaur, also in Calgary, in 2018. This presentation will focus on the historical value of these artworks, discussing their context within their community, along with their preservation needs. We will also review the conservation efforts carried out by CSI, including documentation and assessment procedures, and conservation treatments that ensure the long-term preservation of concrete monuments in the harsh Canadian climate.
