It tells the story of the lords of Flaxlanden. In 1556, the Sundgau belonged to the House of Austria (coat of arms on the left with the horizontal bar called a fess in heraldry) which had given Flaxlanden in fief to the noble family of Masevaux as early as 1368 (in the centre, the two leoparded lions). Christophe, the last of the name, had married Madeleine de Sickingen (right, the five bezants). Both died before 1573 and Flaxlanden then passed to the Bollwillers, then to the Fuggers (1620), to the Rosens (1639) and finally to the Broglies (1779), all powerful and distant lords.
