The Triennial Palace is an excellent example of rationalist architecture and decoration, and like the Park Tower was built in the 1830s. It is one of the most important locations in Italy for everything having to do with design. If you are passionate about design, you can visit one of the many exhibitions that have made the Triennial Palace famous throughout the world. Among other things, you can enjoy a snack here or eat a full lunch in a café overlooking the park: a rarity in Milan!
On the way back to the castle, one last surprise awaits you behind the Triennial Palace: there is a large pool with the fascinating "Mysterious Baths" sculptures. The fountain was designed by Giorgio De Chirico, one of the greatest Italian artists of the first half of the 1900s.
