Why this matters
Ruecallan is a headland in County Antrim composed primarily of basalt, formed during the Palaeogene period (approximately 60–55 million years ago) as part of the extensive basaltic lava flows of the Antrim Plateau. It is notable for its association with the region’s volcanic geological history and the characteristic columnar jointing typical of such formations.
