There are three hypothetical explanations for the origins of the name Siemianowice: either it comes from seven huts which were called Siedminowice/Siedmionowice in Old Polish; from the old legend about Siemion (Siemian), Michał and Maciej, or Siemion, Michał and Jakub; or it comes from ziemia nawa which means earth taken away from water

Spodek (meaning "saucer" in Polish) is a multipurpose arena complex in Katowice, Poland, opened in 1971 at ul. Korfantego 35 under the name Wojewódzka Hala Widowiskowo-Sportowa w Katowicach (Voivodeship Sport and Show Arena in Katowice), under which it is known in the Polish technical/architectural literature, and under which it formally functioned until 1997.
