The SunRing Solstice Observatory marks the Winter and Summer solstices via a circular construction featuring Sun Shadow Casters along Winter and Summer solstice sunrise lines.

The Winter solstice sunrise line has four Circular Sun Shadow Casters designed to project shadows appearing as concentric circles on the SunRing projection wall on the day of the Winter solstice sunrise.

The Summer solstice sunrise line has four Triangular Sun Shadow Casters designed to project shadows appearing as concentric triangles on the SunRing projection wall on the day of the Summer solstice sunrise.

The SunRing remains under construction with considerable material upgrades and enhancements planned.
