Trevellas Coombe
Trevellas Coombe is a valley close to St Agnes and was known as the Blue Hills due to the colour of the slate here. The place name was first recorded in 1302 as the site of the Trevellas family manor. There is a long history of tin mining in the valley. Initially this was "streaming" for alluvial tin and from the 1690s onward, the stream in the valley provided the power for tin processing. By the late 1800s, almost the entire valley was covered with huge sheds and ore dressing machinery.
