A long exposure captures the sandstone coastline contrasting the sea. The Old Head of Kinsale (in Irish, An Seancheann) is a headland near Kinsale, County Cork, Ireland. An early lighthouse was established here in the 17th century by Robert Reading. The area is the nearest point of land (11 miles/18 km) to where the RMS Lusitania was sunk in 1915. The old head of Kinsale was formed by differential erosion. An outcrop of hard sandstone is lodged between two layers of shale. The shale is eroded by marine action at a faster rate than the sandstone. The sandstone anticlines were much more resistant to erosion than the slate filled synclines.
