Peggy Guggenheim Collection, Venice
As art patrons go, Peggy Guggenheim had an eye for the greats. Picasso, Pollock, Miro, Kandinsky and other bohemian masters of the modernist era quickly caught the eye of this wealthy American heiress. She also had an eye for real estate, and her home on the Grand Canal of Venice is now one of the most spectacularly located galleries in the world. Don’t miss: Jackson Pollock’s Alchemy, one of the intense drip paintings that came to define his style and a fine example of why Guggenheim became a champion of his work.
