Curonian Spit sand dunes in Nida, Lithuania
The Curonian Spit is home to the highest moving (drifting) sand dunes in Europe.

The history of the Curonian Spit is dramatic: 5,000 years ago, a narrow peninsula (98 km in length and 0.4-3.8 km in width), the Great Dune Ridge separating the Baltic Sea from the Curonian Lagoon, was formed on moraine islands from sand transported by currents, and later covered by forest.
By the end of the 19th century, a protective dune ridge was formed along the seashore to prevent inland sand migration, and the Great Dune Ridge was reinforced using trees and brushwood hedges.
The most valuable elements and qualities of the Curonian Spit cultural landscape are its unique size and general spatial structure, demonstrating the harmonious coexistence between humans and nature; the characteristic panoramas and the silhouette of the Curonian lagoon; cultural elements including the remains of postal tracks, trade villages from the 10th and 11th centuries, traditional fishermen villages and other archaeological heritage covered by sand; the spatial-planned structure and architecture of ancient fishermen villages turned into resort settlements (ancient wooden fishermen houses, professionally designed buildings of the 19th century, including lighthouses, piers, churches, schools, villas); and elements of marine cultural heritage; natural and human-made elements including the distinctive Great Dune Ridge and individual dunes, relics of ancient parabolic dunes; a human-made protective coastal dune ridge; relics of moraine islands, seacoast and littoral forests and littoral capes; ancient forests, mountain pine forests and other unique sand flora and fauna including a bird migration path; and the social-cultural traditions, spirituality, and the social perception of the area, which reflect the local lifestyle formerly centred on fishermen, artists, scientists, yachtsmen and gliders, travellers and other visitors.
Criterion (v): The Curonian Spit is an outstanding example of a landscape of sand dunes that is under constant threat from natural forces (wind and tide).
