After buying the plot of land in 1697, Prince Eugene had a large park created. The Schloss Belvedere began as a suburban entertainment villa: in 1714 work began to erect what is now called the Lower Belvedere, not as a palace but as a garden villa, with an orangerie and paintings gallery, with suitable living quarters. The architect was Johann Lukas von Hildebrandt, one of the most important architects of the Austrian Baroque, who produced in the complex of buildings his masterwork. He was assisted by the Venetian sculptor Giovanni Stanetti, who had been brought to Vienna by Prince Eugene, with his atelier of assistants; now he also provided properly Italianate sculptural details, such as the figures along the balustrade and garden sculptures.

The Lower Belvedere was finished in 1716. The ceiling of its central Marmorsaal ("Marble Hall"), painted by Martino Altomonte, celebrates Prince Eugene as a new Apollo, leader of the Muses. The room also contains an Apotheosis of Prince Eugene sculpted by Balthasar Permoser. To the west lies a State Bedroom (Paradeschlafzimmer) suitable for levées, a room with delicate grottesche in the manner of Jean Bérain, painted by Jonas Drentwett, the marble-gallery stucco-decorations and figures by Domenico Parodi. The inner marble-room with ceiling-paintings by Giacomo del Po from 1720. The Donnersaal has ceiling frescos by Altomonte and feigned architecture by Gaetano Fanti (1716). To the east a State Dining Room.
The garden was laid out, enclosed by clipped hedging, even as the Belvedere was building, in the formal French manner with gravelled walks and jeux d'eaux by Dominique Girard, who had trained in the gardens of Versailles as a pupil of André Le Nôtre. Its great water basin in the upper parterre and the stairs and cascades peopled by nymphs and goddesses that links upper and lower parterres survive, but the patterned bedding has long been grassed over; it is currently being restored.
