That’s not a submarine periscope jutting from the grass in Náměstí Míru (Peace Square), but a poeziomat that calls up instantaneous poetry read by their Czech and international authors at the push of a button in the original language.
The inventor, Ondřej Kobza (who also installed pianos in public spaces around Prague), built the machine to foster dialogue, social justice, and respect and has earned enough success to install further poeziomats in Kyiv, Berlin, London, and New York.
