The remains of a defence fort built overlooking Coverack during the Iron Age have been uncovered by volunteers.

The Lizard National Trust has been leading a project at Chynalls Point, clearing away blackthorn and gorse to reveal the ramparts (banks or walls) of a promontory fort thought to be around 2,500 years old.

Such forts are defensive structures usually found at the top of steep cliffs, often only connected to the mainland by a small strip of land to reduce the ramparts needed. They are most commonly found in Celtic regions such as Cornwall, Ireland and Brittany.

A spokesperson for the Lizard National Trust said: “Thanks to the help of a volunteer group, we've been able to reveal the ramparts of the Iron Age promontory fort at Chynalls Point near Coverack this week, by clearing away the blackthorn and gorse.

“There are inner and outer ramparts, with an intervening ditch, which cut across the neck of the promontory to create a defended settlement.”
