Coldstones Quarry is situated on Greenhow Hill at 1400 feet above sea level and is one of the highest quarries in Britain. Several small limestone quarries operated around Greenhow over the last two centuries and in the early 1900s the surrounding hills were dominated by stone quarries.
Gradually these closed until Coldstones became the last working quarry in the area. Operated by Hanson,it provides aggregates and asphalt for
major construction projects across the U.K.
Despite its huge size, the quarry is hidden from view by its location and by a protective earth bund.
In 2006, following changes to the quarry boundaries, it was decided to replace a simple existing viewing platform with something more lasting and to provide a significant piece of public art so Hanson Aggregates offered a design commission to Andrew Sabin.
