Large chalk pit or series of pits lying to the south-west of Northfleet Hill, divided centrally by the North Kent railway. Quarrying to the north of the line was established by the late 19th century and continued until the 1930s. These quarries supplied the London Portland Cement Work (now Blue Circle) to the north of the High Street. This was originally achieved via a tunnel situated toward the north-eastern corner of the pit, which extended for some length below The Hill and latterly (post-war) through a second tunnel to the west and below the High Street. Quarrying to the south of the railway started around the 1920-30s and when the quarries the north had been exhausted. A tunnel was bored below the railway line and linked into a reduced eastern tramway.
