Opole is a city located in southern Poland on the Oder River and the historical capital of Upper Silesia. With a population of approximately 128,137, it is the capital of Opole Voivodeship and the seat of Opole County. With its long history dating back to the 8th century, Opole is one of the oldest cities in Poland. It is also the smallest city in Poland to be the largest city in a voivodeship.
The origins of the first settlement are connected with the town being granted Magdeburg Rights in 1217 by 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 due to its position on the intersection of several main trade routes, which helped to generate steady profits from transit trade.
