The landscape was hilly, with the Podole upland covering large part of the Voivodeship. In the north-west there is the Hologory range with the Kamula mountain (473 meters above sea level) as the highest peak (however, the Kamula was located some 5 kilometers beyond the Voivodeship's borderline, in the Lwów Voivodeship). Southern part of the Voivodeship was known for its wineries and peach orchards. The Dniester and the Seret were the main rivers. Border with the Soviet Union was marked by the Zbruch River, along its whole course. Border of the Voivodeship (and at the same time – of Poland) with Romania was marked by the Dniester. The south-easternmost place was the famous Polish stronghold Okopy Swietej Trojcy (Ramparts of the Hole Trinity), which for some time was protecting Poland from the invasions of the Turks and the Tartars. The Tarnopol Voivodeship was created formally on 23 December 1920. It consisted of 17 powiats (counties), 35 towns and 1087 villages. Its capital was also its largest city, with population of some 34,000 (as for 1931). Other important municipal centers of the voivodeship were: Czortków (pop. 19,000), Brody (pop. 16,400), Złoczów (pop. 13,000), Brzeżany (pop. 12,000) and Buczacz (pop. 11,000). The Tarnopol Voivodeship consisted of 17 powiats (counties):  Tarnopol Voivodeship was located in the so-called Poland "B", which meant that it was underdeveloped, with scarce industry. However, agricultural production was good, due to moderate climate and rich, fertile black soil common in these areas of Europe. The southern part of the voivodship was popular among tourists, with the main center in Zaleszczyki – a border-town, located on the Dniestr, where one could spot grapevines, unique to this part of Poland. The railroad network was better developed in the south, with numerous local connections. Major rail junctions were: Tarnopol, Krasne, Kopczynce. On 1 January 1938, total length of railroads within the Voivodeship's boundaries was 931 kilometers (5.6 km. per 100 km²)
