Vegreville egg, Giant egg sculpture in Vegreville, Canada

The Vegreville egg is a 9 m long, 2.5 t sculpture of a Ukrainian pysanka, built over an aluminum framework from anodized aluminum tiles: 1,108 congruent equilateral triangles and 524 three-pointed star hexagons, 3,512 visible facets held by 6,978 nuts and bolts and 177 internal struts. Designed by Paul Maxym Sembaliuk with computer scientist Ronald Resch, it leans at 30° to its base.

The sculpture was created in 1975 as a commemoration of the centennial of the Canadian mounted police force. It also honors the Ukrainian settlement that had developed in the region.

The egg's tiles carry the geometric vocabulary of the pysanka, and the town's Ukrainian Canadian population, settled east of Edmonton, is the reason it was built. Since 2016 the Canadian government has issued commemorative coins shaped like a pysanka, a sign of how widely the sculpture is recognized. The town itself is named after Valentyn Vegrevil, a Catholic missionary priest.

The egg stands on the north side of Alberta Highway 16A in Elk's Park, on the Yellowhead Highway route through Vegreville. It leans at 30 degrees from its base and turns with the wind, so the face you see depends on the day. The site is a roadside stop with open ground around the sculpture.

The entire structure rotates on its base according to wind direction. This ability to move gives the monument a living quality that constantly changes how it appears.
