Name.
Until March 15, 1921, the city was called Alexandrovsk after the Alexander Fortress, founded in 1770. There is no unequivocal opinion in whose honor the fortress was named. The names of Field Marshal General Alexander Golitsyn and Prince Alexander Vyazemsky are mentioned. 
On March 15, 1921, the city was renamed Zaporizhzhia - that is, "located beyond the thresholds." 
The name reminds that before the construction of the Dnieper HPP dam in 1932 at the place where the river crosses the rocky southern edge of the Ukrainian Shield, numerous Dnieper rapids, which hinder navigation, ended.
