Zamek Melnik, Picture 2, Edited Version, Melnik, Bohemia (CZ), 2011

Zamek Melnik dates to the 10th Century, and has been owned by the Lobkowicz family since 1753, although under Communism (1948-1989) the castle was nationalised, along with the castles and estates of other nobles. The castle has had a public winery since 1925 (according to Wikipedia, although there have been cellars, and I'm assuming a private winery, since the 14th Century), which now specialises in organic wine, although the Lobkowicz family are better known for their beer. In addition to the winery, there is also a cukrarna (pastry shop) and a high-end restaurant specialising (as I understand it) in fondue. Self-guided tours are possible (I'm not clear on whether guided tours are done, but I'm assuming they are), and at least one artist was displaying his work in the Big Hall, where the Lobkowicz family normally display their antique map collection. Weddings can also be arranged at the castle.
