A shifting sand dune peninsula that has survived empires, wars, and giantess legends.

In short: The Curonian Spit is a 98-kilometre-long sliver of sand separating the Baltic Sea from a shallow lagoon. Shared by Lithuania and Russia, this ephemeral landscape of drifting dunes and forests has served as a medieval trading hub, a sanctuary for expressionist painters, and a flashpoint for modern environmental disputes.

Formed around the 3rd millennium BC on a foundation of glacial moraine, the Curonian Spit is a geologically fragile feature. It relies on a delicate balance of sand transport and deposition, making it an ephemeral coast element that may eventually be reclaimed by the sea or filled with sediment. Its history is as shifting as its dunes; once home to the pagan trading centre of Kaup, it later fell under the control of the Teutonic Knights and the Kingdom of Poland. By the 18th century, human activity—specifically overgrazing and timber harvesting for naval construction—triggered massive deforestation, causing dunes to bury entire villages.

The 19th and 20th centuries brought profound cultural and political shifts. The area became a magnet for artists and writers, including Nobel laureate Thomas Mann, who spent summers in Nida before his house was seized by the Nazis. Following the world wars, the region was partitioned between Lithuania and Russia, leading to the expulsion of the local German population and the systematic renaming of historic sites. Today, the spit is a UNESCO World Heritage Site, recognized for its unique human-environment interaction, though it remains a site of tension. Environmentalists have long raised alarms over the Kravtsovskoye (D-6) oilfield, located just 22.5 kilometres from the coast, fearing that potential spills could devastate the tourism-dependent economy.

Beyond its political history, the spit is a vital ecological corridor. It hosts the highest moving sand dunes in Europe, some reaching 60 metres in height, and serves as a critical stopover for 10 to 20 million migratory birds each spring and autumn. While the Kursenieki, a Baltic ethnic group once prevalent here, have nearly vanished, the spit remains a protected landscape. Both the Russian and Lithuanian sections are designated as national parks, balancing the influx of modern tourism with the urgent need to preserve a fragile, wind-swept environment that is inherently vulnerable to both natural erosion and human impact.
