Due to regular floods in the Stubai valley bottom, the farmers were looking for alternative land. They found a profitable “quarter” of land at the end of the 13th century in Kartnall (Romanic “quartinale”). The lower and the upper “Kartnallhof” (farmyard) were built, where livestock and dairy farming as well as limited cropping secured existence. Royalties in kind (1/10 of receipts) had to be paid to the owner of the land, the parish of St. Nikolaus in Hall, as a compensation for farming the fields. Today tourism as well as the cows, sheep and goats secure the existence of the two family farms. The animals graze the grassland; their milk is used to produce butter, grey cheese and curd cheese.
