The interior Ballroom of the Palazzo Barbaro was designed by Antonio Gaspari in the early eithteenth century. The four candled chandeliers hang about eight feet off the floor making the ceiling clearance something like 20 feet. The upper curtian windows hide musician's galleries that could be used for dances or chamber music. The ballroom is towards the front of the building and the unseen wall (off frame-right) leads to balconies over the Grand Canal. 

The ceiling decorations by Giambattista Tiepolo are now at the Metropolitan Museum of Art, New York (timeout.com); and the large wall paintings include canvases by Sebastiano Ricci (Fairbrother p. 101). 

John Singer Sargent painted the ballroom in 1898.
