Turner Valley Gas Plant Provincial Historic Site

Horton Spheres Conservation

The most visible symbol of World War II expansion at the Turner Valley Gas Plant are the Horton Spheres. Royalite commissioned these spherical storage tanks in 1942, each with a 5,000 barrel capacity. The Turner Valley Gas Plant stored Turner Valley isobutane in liquid natural gasoline and transported it to the Calgary refinery where it was used to make aviation gasoline.

These Horton Spheres were the first such spheres in Western Canada and are a graphic link to the impact of World War II on the Turner Valley Gas Plant. In 2009, workers sandblasted and repainted these unique parts of our industrial heritage.
