Historic Centre of Riga

Brief description

Riga was a major centre of the Hanseatic League, deriving its prosperity in the 13th–15th centuries from the trade with central and eastern Europe. The urban fabric of its medieval centre reflects this prosperity, though most of the earliest buildings were destroyed by fire or war. Riga became an important economic centre in the 19th century, when the suburbs surrounding the medieval town were laid out, first with imposing wooden buildings in neoclassical style and then in Jugendstil . It is generally recognised that Riga has the finest collection of art nouveau buildings in Europe.

Struve Geodetic Arc

Brief description

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.
