Herakleidon Museum, Science museum in Thissio, Greece.

Herakleidon Museum is a science museum in Thissio, occupying two separate buildings located at 16 Herakleidon Street and 37 Apostolou Pavlou Street near the Acropolis. The dual-site layout allows the museum to present different exhibition themes and provide more space for interactive displays and demonstrations.

The Herakleidon Museum was founded in 2004 by Paul and Anna-Belinda Firos as a non-profit cultural organization at 16 Herakleidon Street in Thissio. During its first decade it staged exhibitions of artists including M.C. Escher, Victor Vasarely, Toulouse-Lautrec, Edgar Degas and Edvard Munch. It later became an interactive center for science popularization and a technology museum focused on the achievements of the ancient Greeks, built around its exhibition "EUREKA, Science, Art and Technology of the Ancient Greeks."

The museum connects science, art, and mathematics by exploring ancient Greek innovations that shaped how we think about technology. Its exhibitions help visitors see how these three fields have always worked together.

The museum is open Wednesday through Sunday from 10 AM to 5:15 PM and closes on major holidays. Plan your visit accordingly to ensure the museum is open, especially if traveling during holiday periods.

The museum displays a full-scale working model of the Antikythera mechanism made from transparent acrylic glass. The clear material reveals the intricate internal gears and mechanisms that powered this ancient computational device.
