The construction of this castle began at the end of the 15th century, in Gothic style. It was subsequently extended and reconstructed, first in the Renaissance and then in the Baroque style. After being abandoned for nearly a century and suffering severe damage during the Napoleonic period, the castle was restored at the end of the 19th century, with the addition of a number of other elements and the landscaping of the surrounding area as a park. Its present form is graphic testimony to its often turbulent history.

Criterion ii: Mir Castle is an exceptional example of a central European castle, reflecting in its design and layout successive cultural influences (Gothic, Baroque, and Renaissance) that blend harmoniously to create an impressive monument to the history of this region.

Criterion iv: The region in which Mir Castle stands has a long history of political and cultural confrontation and coalescence, which is graphically represented in the form and appearance of the ensemble.
