Heraklion Museum of Ancient Greek Technology Kostas Kotsanas

Tucked down a side street in Heraklion, this museum is a genuinely surprising find — it brings ancient Greek technology to life through working reconstructions of inventions and machines you'd never expect the ancient Greeks to have built. Far from the usual dusty-artifact experience, it's hands-on and eye-opening, showing just how sophisticated ancient engineering really was. Part of a wider network of Kostas Kotsanas museums across Greece, this one is worth carving out real time for.
