The White Cliffs of Dover are iconic chalk cliffs located on the southeastern coast of England. Rising up to 110 meters (360 feet) above the English Channel, they stretch for about 13 kilometers (8 miles) along the coastline. The cliffs are primarily composed of chalk, a soft white rock formed from the remains of tiny marine organisms. These cliffs have significant historical and cultural importance, often symbolizing Britain and its resilience. They are visible from the coast of France on clear days and have been a landmark for sailors for centuries. The cliffs are also part of the Dover Strait, a busy shipping route.
