Formerly known as Mountskill Quarry, sandstone was extracted here from the early 1800s until the 1920s. The quarry had its own rail link which took the stone to Ince Pier and onto the barges bound for Liverpool. The rock wall and tunnel were formed during the Triassic period from river deposits and sand dunes. Rowan, silver birch and willow trees recolonised the woodland floor when the working life of the quarry ended. Tits, finches, hedgehogs, woodpeckers, dragonflies and bats can all be seen in the area.
