The Goldbergs started in Oświęcim in the early XIX century to move to Milówka towards the end of the century and arround WW I expand into Bielsko-Biała. 

Sukkah it is. I am sure that Moses Goldberg from Oświęcim who built this house in Milówka and had a hardware store equipped it with a crank mechanism to lift the roof for Sukkot. He was welcoming his guest with the Aramaic/Yiddish - ushpizin welcome to invite the 7 supernal guests "founding fathers" of the Jewish people. At the same time a word sounding like his home town of Oświęcim in yiddish. Way before it was renamed into Auschwitz by the German Nazis. Milówka becomes a tourist destination so Moses changes the house into a hotel and restaurant. It is located on the tourist trail from Milówka rail station into Hala Boracza where in 1925 the first in the world Jewish mountain shelter was built by the Makabbi movement.
