It is divided into 106 rectangle- (70%), square- (20%) and multiform-shaped (10%) blocks and has nine neighborhoods, built along its historical stages:[5] A note about the Romanian Bujak from Sânnicolau Mare and the Moldavian Budjak: The Budjak culture of the North-West Black Sea region is considered to be important in the context of the Pit-Grave or Yamnaya culture of the Pontic steppe, dating to 3,600–2,300 BC.

The Budjak area of the northern Lower Danube was described as the "wasteland of the Getae" by the ancient Greek geographer Strabo (1st century BC).

In fact, based on recent archaeological research, in this period of time, the area was most likely populated by sedentary farmers; among them were the Dacians and the Daco-Romans.

It is generally flat, only slightly fragmented, as a result of water erosion during the time when the Mureș River was able to overflow and uneven deposition of alluvial material.

The territory is located in the Mureș Plain, which is a typical form of fluvio-lacustrine subsidence, with shallow valleys with abandoned riverbeds resulting from the regularization of watercourses and drainage, with an altitude between 80–85 m (262–279 ft).

The Aranca Canal crosses Sânnicolau Mare and in the past aimed to drain water from flooded lands, being widened and deepened in 1959 and 1960.

Western circulation persists in both the cold and warm periods of the year and is characterized by mild winters with liquid precipitation.

Polar circulation is determined by the cyclones in the North Atlantic and is characterized by temperature drops, heavy cloudiness and precipitation in the form of showers, and in winter the snow is accompanied by intense winds.

Tropical circulation causes mild winters and significant amounts of precipitation, and in summer an unstable weather with showers and electric discharges.

The number of winter days (maximum temperature < 0 °C) is low due to the influence of warm and humid maritime air.

In the steppe area, the grassy layer consists of violets (Viola odorata), two-leaved squills (Scilla bifolia) and snowdrops (Galanthus nivalis).

[9] The fauna is of Central European type with sub-Mediterranean elements, with penetrations and a mixture of species coming from the north, south and west of the country.

The fauna of the steppe and forest-steppe is characterized by the presence of rodents such as ground squirrel, hamster, hare, and among the birds: turtle dove, nightingale, quail, grey partridge, etc.

In the Aranca meadow and in the swamps around the town live numerous species of mallards, geese, herons, glossy ibises, fire-bellied toads and otters.

The forest fauna is represented by roe deer, red fox, hare and squirrel, and among the birds are the same present in the steppe and forest-steppe.

Herodotus wrote that in 513 BC next to the Maris (Mureș) river lived the Agathyrsi who were of Thracian origin, engaging in cultivation of the land and even winemaking.

On the left bank of the Mureș, Trajan set up a Roman colony and several cohorts of Legio XIII Gemina, who built here a castrum and a town called Morisena.

Morisena would have covered the entire territory from Cenad to Sânnicolau Mare, being located between the Mureș and Aranca rivers – which at that time was navigable.

Byzantine rhetorician Priscus, sent by emperor Theodosius II, described Attila as having royal authority, dressed simply and very religiously, and learning beautiful things from the Dacians, Hun, Latin and Roman being spoken at his court.

The legends of the time say that Attila was buried on the territory of the town, in one night, in three coffins of gold, silver and iron, together with his weapons and jewelry, on the bed of the Aranca, which was then diverted.

[9] Sânnicolau Mare is mentioned in the papal tithe records of 1332 as a property of the Catholic Diocese of Cenad, named Santus Michael.

Some of the knightly armies of Burgundy, England and the German states passed through the town in 1396, heading for Nikopol, with peasant groups forming here in helping them in the battles against the Turks.

[10] Between 1509 and 1511, the town was hit by a plague epidemic, and in 1514 the local serf peasants took part in the revolt led by György Dózsa, which was suppressed and their leader burned on the red throne.

The capital of Banat falls into the hands of the Turks on 30 June 1552 under Ahmed Ali Pasha, and in the same summer he conquers Sânnicolau Mare and Cenad, the first belonging to the Eyalet of Temeşvar, and the second to the Sanjak of Çanad.

With the Treaty of Passarowitz, the whole of Banat came under Habsburg occupation, the first governor being the cavalry general Claude Florimond de Mercy, who represented the Viennese Court.

In 1751, following the order issued by the Imperial Court in Vienna, Count Kempe proceeded to change and transform the military government into a civilian-provincial administration.

In order to implement this plan, the Imperial House of Vienna decided to colonize German population, which would contribute to a certain extent to the economic development of the province and the promotion of the Roman Catholic religion.

There were also bookstores, weaving mills, pharmacies and a number of craftsmen such as mechanics, tailors, chimney sweepers, rope makers, watchmakers and locksmiths.

[9] The town's economy has seen a trend reversal in recent years, due to its strategic position on the western border of the country, which has attracted a number of important investors.

The emergence in 1860 of the Sokol movement in Czech lands has also an impact on the sports in Sânnicolau Mare, which materializes in 1924, when the Physical Education Society "Falcons of Romania" is created.
