Step back in time and explore one of ancient Greece’s greatest technological achievements — the Antikythera Mechanism, often described as the world’s first analog computer. Take part in a hands-on workshop that reveals how this 2,000-year-old astronomical device worked and why it remains one of the most important discoveries in the history of science. Continue with a guided visit to the Kotsanas Museum of Ancient Greek Technology, led by the museum’s expert guides, to deepen your understanding of ancient Greek innovation. The experience concludes with a relaxing walk through the National Garden of Athens with a licensed English-speaking tour guide, followed by the iconic changing of the Evzones guards at Syntagma Square. This thoughtfully curated experience blends history, science, nature, and local tradition — ideal for families, curious travelers, and anyone seeking a meaningful and non-touristy way to experience Athens.
