Siegenthal
Siegenthal was a village in the vicinity of what is now Brzegi Dolne, in the administrative district of Gmina Ustrzyki Dolne, within Bieszczady County, Subcarpathian Voivodeship, in south-eastern Poland.
The settlement was established in the course of Josephine colonization by Lutheran Germans settlers in 1788. They belonged to the Lutheran parish in Bandrów, but maintained a school during winter with one teacher. They left during World War II. In the years 1945-1951 the area belonged to the Soviet Union, later to Poland. It was eventually depopulated and abandoned in 1946. There are remnants of a Lutheran cemetery.
