Excellent museum in one of my favorite villages we visited in multiple stops across Greece. We found this on a whim when coming to visit the Ancient Olympia grounds and were glad we did. My sons (12 and 8) were really interested in the various puzzles, inventions and exhibits, and loved that a number of the exhibits were hands on. The staff were extremely kind and helpful, available to answer questions or share insight, but also allowing guests to explore on their own. Definitely worth a visit if heading to Olympia, and with no cost (suggested donation) could cover some of the highlights in 30 minutes.
