Maen Castle

Maen Castle is an Iron Age promontory fort near Sennen in Cornwall, built to control the coastal headland. The site uses natural rock faces combined with man-made ramparts to create a heavily defended position overlooking the sea.

The fort was built during the early Iron Age when such fortifications served as critical trading centers. Archaeological finds show the site remained occupied and defended across multiple centuries.

The site shows how Iron Age communities organized their coastal settlements and protected them from threats. Walking here, you can sense how this location commanded views of important sea routes.

The site is accessible on foot with open pathways across the headland offering views on both sides of the coast. Visitors should expect windy conditions and wear sturdy footwear, as the ground is uneven and exposed.

The site preserves rare pottery from a very early Iron Age period found at only a handful of locations in the region. These artifacts help researchers understand when and how people first fortified these coastal areas.
