 The sources which frequently cited the city's 11th-century founding were misinterpreted, and referred instead to the Lower Silesian town of Głogów (Glogau).Given the ages of some texts, a mistake in identifying the first historical mentions of the two settlements is understandable.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.
