This eclectic private museum examines the interrelation of art, mathematics and philosophy, explored through rotating exhibits on such diverse subjects as ancient Chinese technology and shipbuilding. Around the corner in a restored mansion at Iraklidon 16 there is also a kid-oriented permanent science exhibit, though this is open only on Sundays. The museum also holds one of the world’s biggest collections of MC Escher artworks (though it is not always on view).
