The Belvedere Palace is known for its ornamental Baroque architecture and for preserving the elements of other palaces in the 17th century. The stunning landmark was constructed by a renowned architect, Johann Lukas von Hildebrandt. In 1718, Dominique Girard, a French garden architect was summoned for the construction of the Baroque Park. His expertise in the design of the garden and water technology is tangible in the Baroque Pearl. The ceiling fresco in the Upper Belvedere Marble Hall was painted by the great pioneer of the Rococo style Carlo Carlone, while the recent Belvedere 21 was constructed by Karl Schwanzer. The building continues to be an icon of post-war modernism.
