Cathedral Quarry initially dug in 1828 by William Jones Brewer and Job Pictor of Box who were partners at the time, was worked to about 1849 is an unusual quarry that was worked by hand from a vertical shaft as the surrounding quarry owners would not allow access to the stone via their workings. Most of the stone beneath the shaft and area was removed leaving a chamber approx. 40 feet wide, 200 feet long and 80-90 feet high.
There are three distinct levels to the Cathedral – The upper being Box Scallet stone, the middle Box Congrit and the lower level Box Ground stone. After 1890 the only stone worked was the Box Ground having superior properties to the other beds.
Later, Pictor & Sons acquired the whole of Cathedral quarry presumably for access to their own quarries nearby.
