GB1900 Quarries and Collieries
This demonstration viewer displays names relating to Quarries and Collieries from the final GB1900 dataset.
This includes 44,142 names with '*Quarry*' or ' quarry*', and 3,042 names with '*Colliery*' or '*Colly.*'. Although not all of these names relate to real world quarries or collieries, as they also include some names with these words within them, it is estimated that well over 95% of the point features shown relate to former or active quarries or collieries at the time these maps were produced, ca. 1888-1913.
If you keep zooming in beyond zoom level 14, the points should appear against a background OS six-inch to the mile map, as visible in GB1900, with the quarry or colliery named.
It is also possible to toggle the background layer to display a 1950s geological map.
