A History 2

A history of Bath Stone Group and our mines

A young company with

a history stretching back centuries


Bath Stone Group was formed in 2017 when Johnston Quarry Group acquired the original Bath Stone Group, which was founded in 1982, together with a portfolio of assets from Hanson plc. The ‘new’ Bath Stone Group is market leader in the supply of Bath Stone block to the construction community.

Now combined, Bath Stone Group and Johnston Quarry Group are the largest suppliers of block stone into the stone processing community, with annual block sales of over 50,000 tons.

The mines we own and operate have histories and reputations that stretch back centuries.

Stoke Hill Mine

Open cast quarrying at Stoke Hill Mine dates back to the mid-fifteenth century. It is clear it quickly gathered a prestigious name because it was specified for part of the construction of Longleat House in 1568.

Mining at Stoke Hill is likely to have started in the early 19th century. It continued until the outbreak of World War II when the mine was requisitioned by the government and used for ammunition storage. After the war, it remained mothballed until it was acquired by the Bath Stone Group in 1982.

Hartham Park

Hartham Park in Wiltshire has been worked for hundreds of years, although it wasn’t until the 20th century that stone was mined in significant quantities. Like Stoke Hill Mine, Hartham Park was requisitioned by the government during World War II and used for storage. Mining restarted shortly after the end of World War II but the mine was mothballed in the 1950s until the early 2000s. It was acquired by Bath Stone Group in 2017 and mining will restart once again when investment in new mine infrastructure has been completed.
