For 200 years the Octoberfest is located in the same area: The Theresienwiese, a flat area of about 42 hectare in the Munich quarter Ludwigsvorstadt-Isarvorstadt. The area Theresienwiese has its name from Therese von Sachsen-Hildburghausen who married 1810 Prince Ludwig of Bavaria. Their marriage celebration was the first Octoberfest. "Wiese" is the german word for grassland. So "Theresienwiese" means "grassland of Therese". So for an authentic Oktoberfest party, set up tables in near a field and decorate the space with Oktoberfest blue and white helium balloons tied with twine and blue bunting customised with black vinyl letter stickers.
