The Hidden Periscope in Letná Water Tower
took place · 1 Oct 2026
Description was written before the event
Visitors will see the carefully reconstructed interior of the Letná water tower. The building, which had "lost its sight" due to surrounding development years ago, has regained its view through a cleverly hidden periscope - and visitors can try it themselves, perhaps while observing Prague Castle, the Zoo, or the Žižkov Television Tower. The tower also features Foucault's pendulum and a current exhibition.
At the end of the tour, a small surprise awaits: a space that the public normally cannot access will be revealed.
