The promontory fort
Dún na mBó means 'the cattle fort', after the circular fort that once stood at the edge of this headland. The site was excavated during 1999 and belongs to Ireland's group of Iron Age promontory forts.

About
A cliff-top sculpture frames a natural sea blowhole on the wild Mullet Peninsula, where Atlantic swell sprays up through the rock beside the site of an Iron Age promontory fort.
Things to Do
The blowhole and 'Thin Place' sculpture
A pedestrian gate leads in to the sculpture built around the natural blowhole in 2002 by American artist Travis Price and dedicated to all souls lost at sea. A narrow corridor between high walls frames the view down into the hole.
Watch the Atlantic spout
When the waves crash along the cliffs, seawater is forced up and out through the blowhole — it is at its best at high tide or when a heavy swell is running.
Eagle Island Lighthouse views
From the rough cliff top you look out over the Atlantic to the Eagle Island Lighthouse, one of the wildest stretches of the Erris coast.
Sculpture trail and Discovery Point
The site is a Wild Atlantic Way Discovery Point and part of the Tír Saile sculpture trail through north Mayo — an easy add-on to Erris Head and Annagh Head nearby.
