Altrya Sandstone

Altrya Sandstone has been used since ancient times for construction, decorative art works and tools and is recognizable for its distinct pale-yellow colour. It has been widely employed around North Orentia in constructing temples, churches, homes and other buildings, and in civil engineering. Although its resistance to weathering varies, sandstone is easy to work. That makes it a common building and paving material. 
Altrya Sandstone quarries are spread widely across northern North Orentia.
