The wine cellars are situated under the north-eastern (garden) and north-western wing of the chateau. While the cellars under the north-western wing were dug during the baroque reconstruction of the complex, the cellars under the garden wing contain some older pre-baroque structures.
Two wide, still preserved stairways were built to descend to the cellars. A new entrance, dug probably in late 19th century, exited outside the chateau complex and accessed the cellars through a narrow sloping tunnel from the area in front of the Mill Gate.
Although some of the cellar interiors went through a modern conversion, many of their original and typical features are still preserved – such as the massive sandstone walls with rough plaster surface and brick barrel vaults from the baroque period. The walls of the cellars are covered with special mould that creates a microclimate allowing the wines to mature.
It is certain that the project of the large and deep wine cellars keeping constant temperature all-year round had been developed by the builder of the baroque palace, Bishop of Olomouc Karl von Liechtenstein-Castelcorno, who intended to store wine from the bishopric vineyards there. This is the purpose the cellars served since the end of the 17th century and the continuity of this use has been preserved to our day.
