Introduction to the Arc de Triomphe: The Arc de Triomphe (Gloriette) is the highest point of Schonbrunn Palace and is also the viewing pavilion in the garden. The pavilion was built in 1775 and was originally used as a dining room and breakfast room for Emperor Joseph I. There is currently a cafe inside the Arc de Triomphe, and visitors can also climb up the Arc de Triomphe to enjoy the panoramic view of Vienna.
