We heard the story that the "Red House" got its name from the fresh coat of ox blood it received every three years during the middle ages. We're not sure if that means the color or the substance. In any case, the "Red House" was colored red for many centuries.
It was an unusual house. First mentioned in the 1300s, it stood on ancient petrified oak pillars made from trees that were then already centuries old; trees that were alive even before the Crusades! Accessible only by a stairway in a neighboring house, it provided access into the Tuchgaden, or Cloth Merchant's Alley behind it. However, it was best known as Frankfurt's most famous "Schirn", or open-air sausage stand, selling the famous Frankfurter Würstchen, the beloved frankfurter.
Eine Geschichte sagt, das "Rote Haus" habe
seinen Namen von einem frischen Anstrich aus Ochsenblut, den es im
Mittelalter alle drei Jahre erhielt. Wir sind nicht sicher, ob damit die Farbe
oder das Wesen gemeint war. Auf jeden Fall hatte das "Rote Haus" eine
rote Farbe für viele Jahrhunderte.
