Głogówek (pronounced GWO-goo-veck [ɡwɔˈɡuvɛk], German: Oberglogau, Czech: Horní Hlohov, Silesian: Gogōwek) is a small historic town in southern Poland.

The city lies approximately 35 kilometres (22 miles) from Opole, the capital of the voivodeship, and is about 10 km (6 mi) from the Czech border.

The sources which frequently cited the city's 11th-century founding were misinterpreted, and referred instead to the Lower Silesian town of Głogów.

At the time, military conflict in the region was common, and the use of the Głogów fortress may very well have inspired the names of smaller villages in the surrounding area, causing the confusion.

Another error in Silesian record-keeping states that Głogówek, still a fairly small town, had 12 official representatives, a number much too large for a city of that size.

In 1327, Głogówek fell under Bohemian suzerainty, however, it remained under the rule of local Polish dukes of the Piast dynasty until 1532.

Only a few years later, the duke Vladislaus II of Opole (+1401), built another large cloister in Mochów, associated with Częstochowa in the area.

[2] George III Oppersdorff, as a supporter of Catholicism, built several chapels in the 17th century and made the town a regional pilgrimage destination.

[3] Due to his Catholicism, during the Thirty Years' War, he had to take refuge in nearby Poland, where, thanks to the help of Polish king Władysław IV Vasa, he stayed at the Wawel and Niepołomice royal castles.

During the Swedish invasion of Poland, Polish King John II Casimir Vasa stayed in the castle in Głogówek from October 17, 1655, until December 18 of the same year.

Hetman Stefan Czarniecki, poet Jan Andrzej Morsztyn, future king Michał Korybut Wiśniowiecki,[6] and parliamentarian Jakub Sobieski, father of the future king John III Sobieski, also visited the town at that time.

In the Upper Silesia plebiscite mandated by the Versailles Treaty 4,995 inhabitants (95.9%) voted for remaining part of Germany.
