The White Cliffs of Dover are famous chalk cliffs located on the southeastern coast of England, near the town of Dover. They rise about 350 feet (110 meters) above the English Channel and stretch for approximately 8.5 miles (13.6 kilometers). The cliffs are composed mainly of chalk, a soft white rock formed from the remains of tiny marine organisms. These cliffs have significant historical importance, serving as a symbol of Britain and a landmark for sailors crossing the channel. The White Cliffs of Dover are often associated with the Dover Strait, which separates England from France, and have been featured in various songs and literature throughout the years.
