The Herakleidon Museum instantly became one of my favorite stops in Athens. I had no idea how inventive and how ingenious were the Greeks of antiquity. I walked through this compact museum in amazement. The video presentations were marvelous and very realistic. You feel like you are watching history unfold. And also, enjoy a stroll through the beautiful Thissio neighborhood.

The best (most overlooked) museum in Athens! Do not let yourself be turned off by the homepage talking about international art (there is none at the museum) – also feel free to ignore the oddly poetic exhibition ‘currently featured’ (it takes up a tiny space in this 2-building museum and has no relevance for the ongoing exhibition). What you should do: Spend time dwelling on the ongoing exhibition in writing and video about adventurous innovations in ancient Greece: From the Antikythera Mechanism (an analog computer as thrilling as any Mission Impossible meets Indiana Jones story) to the captivating story about the tunnel of Eupalinos. Beautiful museum featuring lots of chairs enabling you to dwell.

What an unexpected treat. Small museum but delightful exhibits which include models of how ancient greeks got things done, how they built ships and propelled them, how they assembled the parthenon, how they fought their enemies. Only 6 euro, about one hour duration. A lot of fun

Small museum in 2 parts, the larger on a side street. We only went because we passed by on a walk. Inside were excellent displays of Mycaenaen and Athenian science, engineering and mathematics. Want to know what a trireme looks like? How the walls of Athens were defended (and attacked)? How the Parthenon was built? It's all here, along with some really quirky inventions. Highly recommended.
