The Museum's Old Wing houses the entire collection of works by the Andriot sculptor Michael Tombros. In the same space works by some of the most important representatives of modern Greek sculpture are permanently exhibited (Zongolopoulos, Takis, Sklavos, Chryssa, Benglys, Nikolaidis, Pappas, etc.).

During the winter period (October-May) the galleries of the New Wing house part of the Foundation's permanent collection, mostly works of contemporary Greek artists (Chryssa, Fassianos, Pavlos, Kounellis, Tsoklis, Psychopedis, Tetsis, etc.), but also a number of works of important international artists (Rodin, Richier, Cesar, Hepworth, etc.).
