built upon the foundations of the ancient Greek town of Antipolis

Today, this lovely castle houses one of the world's greatest Picasso collections.
The great artist spent half of 1946 living and painting in the castle.
When he departed, he gave the museum all the work he created while in residence:
24 paintings, 44 drawings, 32 lithographs, 11 oils on paper, 80 pieces of ceramics,
2 sculptures and 5 tapestries. It is truly a diverse and fascinating collection
showing the many sides of Picasso's art
