Mykolayiv district was founded on December 6, 1966 with the centre in Mykolayiv town.
The district is located in the central part of Lviv region, the north part of the district is in Opillya (rugged and ripply plain), and its south part is within Prykarpattya boundaries. The Dniester river flows through the territory, and a lot of ponds (especially fishing ponds) adjoin the river. Mykolayiv district square is 692 km2, it is 3.2% of Lviv region territory and it forms 0.1% of the territory of Ukraine. On the district territory the town of regional importance Novy Rozdil is situated.
The population is 65.9 thousand (2003), and it forms 3.1% of Lviv region population.
Across this district from the North to the South the international roads Lviv — Uzhgorod — Budapest and Lviv — Stryi — Chernivtsi and an electrified main railway line Lviv — Stryi — Chop lie.
The district is rich for limestones, marls, quartz sand, clays for bricks producing, natural sulphur deposits. Natural gas stores are also found out there. The district is industrial and agrarian. Different industries are developed here: building materials industry, in particular — cement, facing and silicate bricks, lime, prefabricated reinforced concrete dalle, facing, road and pavement tiles, building sand, glassware, beer, soft drinks, bakery articles, meat and dairy produce, fish breeding, sugar beets, grain, potatoes and vegetables cultivation. Specialization — building and installing common and special works and transport service. In Novy Rozdil town the chemical factories are placed, and in particular they are acids and mineral fertilizers producing and machine manufacturing factories.
In the 19th century the territory was settled by the German colonists. There were settlements which do not exist now, they were given new names: Lindenfeld is called Lypivka now, Dornfeld is called Ternopillya, and the rest were just joined to other villages. In 1860 in one colonist's family in Mykolayiv a small girl called Julia Shneider was born, who is mostly famous as Ukrainian poetess Ulyana Kravchenko.
The poet Mykola Ustyjanovych and the Shukhevyches family (the first member of that family — Ivan Shukh was born in Rozvadiv village) also come from Mykolayiv district.
The most interesting and mysterious object in Mykolayiv district is a former capital of the White Croats Stilsko (VIII-IX cent.) and a big pagan sanctuary in the neighbouring village Iliv.
This is one more district which lacks tourists' attention. It is a pity, because it has a great amount of monuments, interesting sites and mineral springs.
