The Kotsanas Museum is a clever Athens detour for travellers who have had their fill of broken marble but still want ancient Greece. Its displays focus on working reconstructions: automata, measuring devices, musical instruments, lifting machines, and the technological imagination behind objects such as the Antikythera Mechanism.
The museum is small and central, in Kolonaki near Syntagma, so it works well between bigger sights. It is especially strong with curious children and adults who like to touch mechanisms, ask how things worked, and see antiquity as practical engineering rather than just sculpture and myth.
