The Southwell quarry is situated along the south eastern coast of Portland. This limestone quarry extends along the east of Portland Bill road, from Southwell all the way to the Portland Bill Observatory.
Southwell quarry has reserves of over 1,264,000m³ and will be worked in the future. This equates to over 63 years of quarrying or mining.
The site will be worked in a north to south direction in small phases, allowing for restoration to minimize the impact to this sensitive area.
