This educational leisure park was created in 1980 by the Association "Maisons Paysannes d'Alsace" which rebuilt the first house on the site, the Koetzingue house, on a plot of land in Ungersheim, in the wasteland of the Potash Mines. Little by little, other houses were added and on June 1st 1984, the Ecomusée d'Alsace opened its doors. It was inaugurated by Jack Lang, Minister of Culture. The museum pursues its mission through activities aimed at promoting the customs of yesteryear and the local heritage.
