Human habitation of this elongated sand dune peninsula, 98 km long and 0.4-4 km wide, dates back to prehistoric times. Throughout this period it has been threatened by the natural forces of wind and waves. Its survival to the present day has been made possible only as a result of ceaseless human efforts to combat the erosion of the Spit, dramatically illustrated by continuing stabilisation and reforestation projects.
Since 2000 it is a Unesco site.

The Vilnius Historic Centre began its history on the glacial hills that had been intermittently occupied from the Neolithic period; a wooden castle was built around 1000 AD to fortify Gedimino Hill, at the confluence of the Neris and Vilnia rivers. The settlement did not develop as a town until the 13th century, during the struggles of the Baltic peoples against their German invaders. By 1323, when the first written reference to Vilnia occured, it was the capital of the Grand Duchy of Lithuania. At this time, some brick structures had apparently been erected on a small island formed when the Vilnia changed its course. By the 15th century, the Grand Duchy of Lithuania, with its capital Vilnius, had become the largest country in Europe, stretching from the Baltic Sea in the North to the Black Sea in the South. The historic centre comprises the areas of the three castles (Upper, Lower and Curved) and the area that was encircled by a wall in the Middle Ages. The plan is basically circular, radiating out from the original castle site. The street pattern is typically medieval, with small streets dividing it into irregular blocks, but with large squares inserted in later periods.
Since 1994 it is a Unesco site.

The Struve Arc is a chain of survey triangulations stretching from Hammerfest in Norway to the Black Sea, through 10 countries and over 2,820 km. These are points of a survey, carried out between 1816 and 1855 by the astronomer Friedrich Georg Wilhelm Struve, which represented the first accurate measuring of a long segment of a meridian. This helped to establish the exact size and shape of the planet and marked an important step in the development of earth sciences and topographic mapping. It is an extraordinary example of scientific collaboration among scientists from different countries, and of collaboration between monarchs for a scientific cause. The original arc consisted of 258 main triangles with 265 main station points. The listed site includes 34 of the original station points, with different markings, i.e. a drilled hole in rock, iron cross, cairns, or built obelisks.
Since 2005 it is a Unesco site.
