Originally, meadows, pastures, floodplains and groves were intertwined with the islands and branches of the Danube in today's part of the city. For the first time, in the eastern part, people settled 3,500 BC BC in Vlčom hrdle (the current Slovnaft complex). They dealt with pastoralism, agriculture, logging, built flood defenses, against the waters of the wide branched Danube. Near Bratislava, two fords led across the Little Danube. The village of Prievoz was established near the upper one. The coat of arms of Prievoz later became the coat of arms of the city district.
