In 1978, the painter’s son, Elias Gounaropoulos, donates his father’s atelier and 40 of the latter’s oil paintings and drawings to the Municipality of Zografos. Thus the G. Gounaropoulos Museum is born, and opens for the public on February 8, 1980.

In 1994, the Municipality of Zografos expands the museum adding a new building next to the old atelier of the painter (which has been listed by the Greek State as conservation-worthy property). Thus, the new building supplements the function of the main museum; the Centre for Art and Culture hosts a variety of temporary art exhibitions, lectures and other cultural events.
