Opole County in the context of "Dobrzeń Wielki"

Opole (Polish: [ɔˈpɔlɛ] ; German: Oppeln; Silesian: Ôpole; Silesian German: Uppeln) is a city located in southern Poland on the Oder River and the historical capital of Upper Silesia. With a population of approximately 127,387 as of the 2021 census, it is the capital of Opole Voivodeship (province) and the seat of Opole County. Its metropolitan area was home to 146,522 inhabitants. It is the largest city in its province.

Its history dates to the 8th century, and Opole is one of the oldest cities in Poland. An important stronghold in Poland, it became a capital of a duchy within medieval Poland in 1172, and in 1217 it was granted city rights by Duke Casimir I of Opole, the great-grandson of Polish Duke Bolesław III Wrymouth. During the Medieval Period and the Renaissance, the city was known as a centre of commerce; several main trade routes intersected here, which helped to generate steady profits from transit trade. The rapid development of the town was also caused by the establishment of a seat of regency in Opole in 1816. The first railway connection between Opole, Brzeg and Wrocław was opened in 1843 and the first manufacturing plants were constructed in 1859, which greatly contributed to the city's regional significance.
