Mikulov Castle is in the town of Mikulov in South Moravia, Czech Republic. The castle stands on a place of historic Slavonic settlement, where since the end of the 13th century the original stone castle was erected. The present castle is the result of a reconstruction in 1719–1730 under the princes of Dietrichstein. The end of World War II meant a complete disaster for the castle, as German troops withdrawing from the town set fire to it.
After an extensive reconstruction in the 1950s, the castle became the seat of the Regional Museum in Mikulov, housing art and historical collections, including artifacts relating to the history of local wine production. The Renaissance wine barrel, dating from 1643 and one of the largest, 1,014 hectolitres (22,300 imp gal; 26,800 US gal), wine barrels in Central Europe, is on display.
