Boryslav
Summary
Boryslav (Борислав; Borysław) is a city located on the Tysmenytsia (a tributary of the Dniester), in Drohobych Raion, Lviv Oblast (region) of western Ukraine. It hosts the administration of Boryslav urban hromada, one of the hromadas of Ukraine. Boryslav is a major center of the petroleum and ozokerite industries. Population:
The area of the modern town of Boryslav has been inhabited at least since the Bronze Age. There are remnants of a pagan shrine from the 1st millennium BC located in the area, where approximately 270 petroglyphs are found, mostly depicting solar signs – symbols of a pre-Christian Solar deity.
Between the 9th and 13th centuries, the site of the modern town housed a fortress named Tustan, which was part of a belt of similar strongholds defending the Kievan Rus' from the west and south. After the dissolution of Kievan Rus', the town became a part of the Halych-Volhynian Principality.
With the collapse of the latter, in 1387 Boryslav became a part of the Crown of the Kingdom of Poland. In 1772, during the Partitions of Poland, it was annexed by Austria and became a part of the Austrian Kingdom of Galicia and Lodomeria.
One of the great technological developments of the 19th century was the discovery by pharmacists Johan (Jan) Zeh (:uk:Зег Ян, :pl:Jan Zeh) (1817–1897)) and Ignacy Łukasiewicz, in nearby Lviv, of technology that led to the establishment of a new industry based on petroleum. Scientists worked out a method of distilling Boryslaw crude oil, and on 30 March 1853 made the first kerosene lamp. As early as 31 July 1853 their new lamp was used to illuminate the Public Hospital in Lviv. Their discoveries marked the beginnings of the rapid search for petroleum in the Carpathians — especially in the eastern sector of the mountain chain where rich oil deposits were discovered. In 1854 the first ozokerite mine was started in the town after the ore was discovered by Robert Doms.
