The small valley named after the municipality of the same name is located west of Haugsdorf in the north of the Weinviertel wine-growing region in Lower Austria. Probably there was already viticulture here at the beginning of the first millennium. This is vouched for in the year 1140, when the Maltese Order of Knights in "Mourberg" was given land with vines. Today, the Castle Winery of the Order of Malta is run at this historic site. The area is, so to speak, formed as an island on the south-eastern slopes of the Buchberg. It has a very special microclimate with intensive sunshine, which is ideal for viticulture and also favours the production of red wine.
