Often hearing about a place called "Three Castle Head", one day, while taking some postcard-style photos of sheep, a man decided he had to find out if it was true.

A man gave him directions to the rumoured castle. "Walk over the hill in this direction for 35 minutes" was what he said.

There was no path.

The hike was muddy.

This was the only human habitation he saw on the half-hour walk.

And there it was. Three castles. The stories were true. Built in 1207 apparently.

The big castle looked to be in great condition. Dry masonry construction, apparently.

Most surprising was the 200ft drop to the jagged North Atlantic coastline of Ireland, just west of the castle. Proper waves and rocks.

Here is the main castle, as he looked for an entrance.

This arch looks promising.

There was an elaborate rusted lock on the gate.

It seemed to be rusted shut. The castle was spacious.

There was a passageway in the roof.

The two other castles were smaller, probably some sort of watchtowers.

This one beside the lake was in good condition.

The courtyard of the watchtower.

This gate was open! He had to go inside.

A rocky floor, no traps visible.

The walls had lots of small windows.

View from a window, quite beautiful actually.

There had been previous visitors, this looks like a toothbrush, somebody must have spent a night here.

Looking out through the door.

Finally, the middle castle was the smallest and most ruined, with a modern gate on the front wall.

Lots of pieces of iron inside, a substantial space.

He couldn't get in, but I stretched my arm through the gate, around the corner with my phone to grab some photos.

And that was it. It might be worth returning with a drone or some free running friends. Dunlough Castle, it's called. Here's a token shot of some sheep on the coast.
