bluestones
Welsh ancient monoliths
Bluestones are types of building or paving stone that have a bluish-gray color.
The term most famously refers to the smaller stones at Stonehenge, transported from Wales to the monument site.
In different regions, bluestone designates various geological types: in the northeastern United States it typically means a blue-gray sandstone used for sidewalks and patios, while in Australia and New Zealand it refers to basalt used in historic buildings and streets.
