50 Litas coin dedicated to the Curonian spit (UNESCO World Heritage).

The Curonian Spit (Lithuanian: Kuršių Nerija, Russian: Куршская коса, German: Kurische Nehrung, Latvian: Kuršu kāpas) is a 98 km long, thin, curved sand-dune spit that separates the Curonian Lagoon from the Baltic Sea.
The Curonian Spit stretches from the Sambian Peninsula on the south to its northern tip next to a narrow strait, across which is the port city of Klaipėda on the mainland of Lithuania. The northern 52 km long stretch of the Curonian Spit peninsula belongs to Lithuania, while the rest is part of the Kaliningrad Oblast, Russia (see the map). The width of the spit varies from a minimum of 400m in Russia (near the village of Lesnoye) to a maximum of 3,800 m in Lithuania (just north of Nida).
