West Cornwall is rich in prehistoric and ancient remains, and Chûn Castle is one of the most spectacular. Perched on a hilltop looking out over the cliffs to the Atlantic Ocean, there is still enough left of the Iron Age defensive fort to give visitors an idea of what life must have been like on these moors in the years before the birth of Christ. The gateposts still remain, as do the foundations of the walls which once towered twenty feet over the hilltop. Within the ramparts can be seen the remains of stone houses constructed by people who re-inhabited the castle in the Dark Ages, after the departure of the Romans.
