The Municipal Library of Prague has a very cool book tower. This book Tower is assembled by Matej Kren. a Slovakian born Artist. Matej Kren’s ‘Idiom’ book tower originally appeared in Sao Paulo’s International Biennial in 1995. But is now a part of the Municipal Library of Prague.
I found this piece of art when I visited Prague Last year and found this while googling for best places to visit in Prague.
Later I found out that I also read something about this tower here on local guides connect by this Article shared from @TheEagleEye Thank you for sharing.
I also shared a video and some pictures on google maps, of course, check them out here
