Smolenice Castle was built in the 15th century, but it was destroyed during Rákóczi's War of Independence and Napoleanic wars. In 1777, Count János Pálffy from Pezinok inherited Smolenice but did not reside in the castle due to its poor condition and lack of money for rebuilding it. The castle was only rebuilt in the 20th century, by order of Count József Pálffy. The architect Jozef Hubert designed the new castle by using Kreuzenstein castle near Vienna as a model, and the works were controlled by the architect Pavol Reiter from Bavaria. During its construction there were masters from Italy, Germany, Austria and Hungary, and 60 workmen from Smolenice and nearby villages. The main building has two wings and a tower, and is made of ferroconcrete.
