Oslavany Chateau, Renaissance chateau in Oslavany, Czech Republic

Oslavany Chateau is a Renaissance building erected by the Althans at the end of the 16th century in front of the western wall of the former Cistercian monastery. Its two arcaded wings are carried by 102 sandstone columns, and an octagonal bell tower built in 1712 rises above the chapel.

The building started as a Cistercian monastery and was later transformed into a nobleman's residence as each era left its mark through different building styles. These changes show how the owners' preferences and needs shifted over time.

The chateau's chapel tower received a new octagonal bell tower in 1712, built on the orders of abbess Maria Rosa. Its tower was repaired in 1958 and again above the chapel in 2003. Since 1999 the chateau has hosted the Historické oslavanské slavnosti every September.

The chateau stands in the centre of Oslavany; the west wing has housed the Museum in Ivančice since 2024, with a lapidarium exhibition running since 2020, while the south wing holds the Mining and Energy of the Rosicko-Oslavany Region and Firefighting Museum displays. The Zámecká restaurant and the first-floor salons and costume room of the Divadlo na mýtině theatre are also in the building.

The building stands out for its rare blend of two architectural styles that do not usually appear together, making it architecturally distinctive. This unusual combination resulted from preserving Romanesque sections when the property was redesigned.
