HER Info (unless otherwise noted)
This is the site of a colliery called the Old Engine owned and operated by the Delaval family. It may have been a small bell pit form of mining that was practised here - it was dug or 'sunk' to the coal levels called 'seams' before 1761. The exact dates this site worked are unknown. It was linked to the Seaton Sluice harbour by a wagonway which also carried the coal for a number of other mining sites which are now to be found across the county boundary.
