Housed in an impressive modern structure with four marble towers, glass passage ways and rooftop terraces, the Museum of Contemporary and Modern Art has works by French and American artists from the 1960s, including Andy Warhol, Roy Lichtenstein, Jean Tinguely, Niki de Saint-Phalle and the Ecole de Nice. You can't miss the massive "La Tête au Carré de Sosno" between the museum and the Acropolis Convention Center. Admission is free.
