Strūve Park

In 1797 the town pastureland was marked in the place of Jēkabpils plan where Strūve Park is located today. In 1820 the territory was planted with trees according to corvee procedure and after the initiative of Jēkabpils Town Secretary Klauss to create a garden.

It became famous thanks to the professor of astronomy Wilhelm von Struve (1793 — 1864) of Tartu University who performed geodetic and astronomical measurements at the park during summer 1826 for the calculations of meridian arc.

In 2005 the decision on inclusion of a unique object, i.e., Struve Geodetic Arc, into UNESCO World Heritage List was adopted during the 29th Session the World Heritage Committee. The thirty-four points which have been marked in territories of ten countries with special signs made of iron or stone remind of the meridian arc measurement works organised internationally at the beginning of the 19th century.

They had a significant effect on the further development of science and assisted in determining the exact dimensions and shape of the Earth.

Struve Geodetic Arc as a cultural object is unique, since it is situated in territories of several countries. Struve Geodetic Arc was measured in the period from 1816 to 1855. It stretches from the Norwegian coast of the Arctic Ocean to the Danube estuary by the Black Sea with total length of 2 822 km. On the land surface the meridian arc is marked with geodetic points in territories of ten countries, i.e., Norway, Sweden, Finland<Russia, Estonia, Latvia, Lithuania, Belarus, Ukraine and Moldova.

In Latvia there is a total of 16 points amongst which the astronomical observation station Jēkabpils is the most significant. It was established and measured in May-June 1826. Determination of geographical coordinates was complicated in expedition conditions at the beginning of the 19th century. Inappropriate stationary instruments and balance wheel clocks of observatories were used for the astronomical observations.

During time the astronomical station Jēkabpils remained undestroyed. When establishing the Class I Triangulation Network of Latvia, in 1931 Struve Geodetic Point was once again reinforced and covered with memorial stone presented to his town by Eduards Valters, teacher of natural sciences at Jēkabpils Gymnasium.
