Sister cities of Borschiv

Borshchiv has been mentioned under its name as the Dudynsky family manor since 1456. In 1629 the town was granted a Magdeburg charter. In 1672–1683 the town was controlled by Ottoman Turks. After the First Partition of Poland, the town was annexed by Austria-Hungary. In 1809–1815 it was controlled by the Russian Empire and then returned to Austrians. In 1914–1917 it was taken over by the Russian troops again. From 1919 to September 1939 it belonged to Poland and in September 1939 was annexed by the Soviet Union. After a short period of rule by the Germans at the beginning of World War II it was ceded back to the Russians until the fall of the USSR and declaration of Ukrainian independence.

The Borshov Horizon or Borshovian Horizon is a geological layer of marl and limestone formed in the lowermost Devonian period. Typical specimens of this province have been recorded in the Upper Dniester valleys near Borshchiv where it reaches the surface layers of the land. It is marked by the presence of microscopic Margachitina chitinozoans, certain trilobites and bryozoa dispersed in grainstone. According to Pushkin, waterborne Bryozoa living in shallow lagoons were the dominant life form that shaped the Borschovian plains. Some areas of the Borschovian layer were dominated by colonies of a single species where others were populated by a mix of different Bryozoa.
