Tarnów () is a city in southeastern Poland with 105,922 inhabitants and a metropolitan area population of 269,000 inhabitants. The city is situated in the Lesser Poland Voivodeship since 1999. From 1975 to 1998, it was the capital of the Tarnów Voivodeship. It is a major rail junction, located on the strategic east–west connection from Lviv to Kraków, and two additional lines, one of which links the city with the Slovak border. Tarnów is known for its traditional Polish architecture, which was influenced by foreign cultures and foreigners that once lived in the area, most notably Jews, Germans and Austrians. The Old Town, featuring 16th century tenements, houses and defensive walls, has been preserved. Tarnów is also the warmest city of Poland, with the highest long-term mean annual temperature in the whole country. Companies headquartered in the city include Poland's largest chemical industry company Grupa Azoty and defence industry company ZMT. The city is currently subdivided into 16 districts and is a member of the Association of Polish Cities (Związek Miast Polskich). Names and etymology The first documented mention of the settlement dates back to 1105, spelled as Tharnow. The name later evolved to Tarnowo (1229), Tarnów (1327), and Tharnow (1473). The place name Tarnów is widely used in different forms across Slavic Europe, and lands which used to be inhabited by Slavs, such as eastern Germany, Hungary, and northern Greece. There is a German town, Tarnow, Greek Tyrnavos (also spelled as Tirnovo), Czech Trnov, Bulgarian Veliko Tarnovo and Malko Tarnovo, as well as different Trnovos/Trnowos in Slovenia, Slovakia, Serbia, Bosnia, and North Macedonia. The name Tarnów comes from an early Slavic word trn/tarn, which means "thorn", or an area covered by thorny plants. History Already in the mid-9th century, on the Tarnów's St. Martin Mount (Góra sw. Marcina, 2.5 kilometers from the centre of today's city), a Slavic gord was established, probably by the Vistulans. Due to efforts of local archaeologists, we know that the size of the gord was almost 16 hectares, and it was surrounded by a rampart. The settlement was probably destroyed in the 1030s or the 1050s, during either a popular rebellion against Christianity (see Baptism of Poland), or Czech invasion of Lesser Poland. In the mid-11th century, a new gord was established on the Biała river. It was a royal property, which in the late 11th or early 12th century was handed over to
