Anotations

Scope note:

A tough, gritty sandstone used for building, found in Yorkshire and other areas of England; it is the principal stone of the Southern Pennines, the heart of the gritstone region. It is characterized by the angularity and large size of its quartz grains. There are many varieties of gritstone, some of which are quite strong. It was quarried by the Romans, was in use again before the Norman Conquest, and continues to be used in modern times.
