Devon Island is the world’s largest uninhabited island, a barren and frozen place that is used by NASA scientists to carry out research on the practicalities of missions to Mars.

The attractive town of Cobh is situated on an island in Cork Harbour, one of the largest natural harbours in the world.

Qaanaaq is the northernmost town in Greenland and one of the most northerly settlements in the world, still popularly known as Thule after the ‘ultima Thule’ of antiquity. The town’s 600 hardy inhabitants endure permanent darkness in winter, while summer brings four months of 24-hour daylight.
