The existing palace was remodeled and expanded by two architects, Nikolaus von Pacassi and Johann Ferdinand Hetzendorf von Hohenberg. The Baroque palace became the summer residence of kings and emperors of the empire from the mid-18th century until the end of the Holy Roman Empire in 1806. And the summer residence of the Austrian imperial family - from 1804 until the end of World War I.
During this time the palace, with its court of several hundred people, was the cultural and political center of the Habsburg Empire.
