Klementinum Tower highlights

Guided access through Baroque interiors

Your ticket includes a guided walk through the Klementinum’s historic halls. Guides explain the site’s role in science, literature, and education, setting the stage for the library and tower.

Baroque Library Hall viewing point

The library is seen from a designated viewing spot at the doorway. From here you can observe the frescoed ceiling, historical globes, and richly decorated bookcases that define the hall’s atmosphere.

Meridian Room and scientific instruments

The Meridian Room preserves tools used to mark the exact moment of noon and track astronomical movement. Historic charts and instruments illustrate the building’s original purpose.

Tower gallery with castle-facing views

A steady stair climb leads to an open-air platform with views toward Prague Castle and across the riverfront. The compact gallery offers rewarding perspectives in morning and late-afternoon light.
