Nysa

Nysa was probably founded in the 10th century. The name of the Nysa river, from which the town takes its name, was mentioned in 991 when it was part of the Duchy of Poland under Mieszko I. A Polish stronghold was built in Nysa in the 11th and 12th centuries due to the proximity of the border with the Czech Duchy. From the 14th century on it was administered by the Bishopric of Wrocław. Nysa was granted town rights around 1223 and attracted Flemish and German settlers. In 1241 it was ravaged by the Mongols during the first Mongol invasion. In 1245, it was granted staple right and two yearly fairs were established. Nysa became an important trade and craft center of Poland before it passed under the suzerainty of the Bohemian Crown in 1351, under which it remained until 1742.

The town's fortifications from 1350 served to defend against the Hussites in 1424. During the Thirty Years' War, it was besieged three times. It was looted by the Saxons and Swedes. During the First Silesian War in 1741, it was captured by Prussians. In 1758 it was unsuccessfully besieged by the Austrians and stayed Prussian.

Towards the end of WWII, about 80% of the city center was destroyed. Most affected were the houses on the Rynek (Market Place) and the houses along the main streets.
