It is likely that Lambshouse Quarry originated at the cliffs at the north of the cove while Gull Point was to the south.

The quarry site cuts a deep "D" shape into the cliffs immediately due south of the Tintagel youth hostel building and is known as Lambshouse Cove.

A "box cave" at sea level produced a darker green slate considered to be of higher quality.

The best preserved of these which served Gull Point quarry still has its intact mechanism pit and cable tunnels.

One of the most striking features of Lambshouse Quarry is the giant spoil tip cascading down the cliffs to the sea.
