Rokiškis was first mentioned in historical sources in 1499. The Krošinskiai, Tyzenhauzai and Pšezdzieckiai families are associated with his name. The manor house of classicist architecture arose in 1801, behind which a mixed planning park was established. In 1905 the palace was rebuilt and acquired Gothic, Renaissance and Baroque elements. Now the manor houses the Rokiškis Regional Museum.
