Opposite the central square in Katakolo, (under the auspices of the Μunicipality of Pyrgos), the Museum of Ancient Greek Musical Instruments and Toys & Games "Kostas Kotsanas" houses approximately 50 (reliably operating) reconstructed musical instruments and toys & games of the ancient Greeks.

The exhibits are accompanied by rich audio-visual material (in Greek and English), while many of them are interactive.

The exhibition (categorised in thematic units) follows the modern educational perception in Pedagogic and Museum Education so that it acts multileveled as far as the greatness of ancient Greek technological thought and technique is concerned.
