This educational centre devoted to science and technology includes Athens' planetarium, a 950-sq-metre hemispherical dome on which 3D virtual trips to the galaxy, as well as IMAX movies and other shows, are screened. There is simultaneous narration in English (€1, or bring your own headphones to plug in).
Also here is the Athena Science & Technology Centre, offering two floors stacked with 54 interactive exhibits, as well as experimental demos and workshops.
