kawz'way, a remarkable promontory, projecting from the north coast of Antrim, Ireland. It is formed by a mass of basalt from 300 to 500 feet in thickness. The causeway extends for about 300 yards and is formed of the tops of about 40,000 closely fitting basaltic columns, which have the form of six-sided prisms. The diameter of the columns varies from 15 to 20 inches, and each is divided into sections of nearly equal length. The entire structure is divided into three causeways, known as the Little Causeway, the Middle Causeway, or Honeycomb, and the Grand Causeway. The Little Causeway has a variety of pillars, some being hexagons, others octagons and still others pentagons. In the Middle Causeway an arrangement of columns forms a chair, known as the Wishing Chair, and the Grand Causeway contains a structure known as the Lady's Fan, from its resemblance to this article. Another arrangement of columns forms the Giants' Loom, and still another, the Giants' Well. The promontory takes its name from an ancient legend which attributed its construction to giants, who commenced to build a road across the channel to Scotland.
