 Apponyi Castle was built up by the Apponyi family in various phases from the 16th to the early 20th centuries.A major addition was the construction in the mid-19th century of a dedicated new wing to host the Apponyi Library following its transfer from Bratislava.The castle was inhabited by a number of members of the family, including Count Lajos Apponyi (1849-1909) and his two sons, Gyula (1873-1924) and Henrik (1885-1935), the last occupant from the family.
