Перевод:

Николаев — город на юге Украины, административный центр Николаевской области. Имя свое он получил через год, после победоносного штурма Очакова российскими войсками под командованием А.В. Суворова. Очаков был взят в декабре 1788 года, в день Святого Николая, защитника моряков. В его честь и назвали новый город.
Судостроению и флоту полностью была подчинена жизнь города.  Именно в Николаеве В.И. Даль, находясь на воинской службе, приступил к созданию «Толкового словаря живого великорусского языка».
В городе побывало множество русских деятелей культуры.
