Nikolaev is a city in the south of Ukraine. It is a district and regional center. Located on the peninsula, it is the port of the Black Sea. Within the city, there are two rivers – the Southern Bug and Ingul, and road bridges have been built across them. It was built according to the plan, with straight streets and neighborhoods of a clear shape, despite the complexity of the relief. Founded as a shipyard, it did not have a name for about a year. It received its name in memory of the capture of the Ochakov fortress on the day of St. Nicholas – the patron saint of sailors in 1788. The construction of sailing warships defined the main industry.

In Soviet times, the city was one of the most important regions for shipbuilding. The port and convenient transport routes made Nikolaev a large industrial center. Now the city is crossed by the M-14 highway and the strategic European route E58. On the territory of the region there are about 700 km of railway tracks connecting Nikolaev with Kiev, Odessa, Voznesensk, Crimea, Donbass, etc.
