A Closer Look at the Tour Experience

This guided tour of the Klementinum begins with a meeting point in the middle of the complex, near the Mirror Chapel—an easy-to-find location with precise GPS coordinates. Once you exchange your voucher at the ticket office, you’re ready to step into one of Prague’s lesser-known yet most impressive sites.

Exploring the Klementinum Complex

The Klementinum dates back to 1653 and is now primarily home to the Czech National Library. The complex sprawls across a full city block, and its architecture is a stunning mixture of Baroque, Renaissance, and Rococo styles. You won’t be able to access the entire complex during the 45-minute tour, but your guide will lead you through the highlights.

The Baroque Library Hall

Arguably the most famous part of this tour is the Baroque Library Hall. From behind a fence, you can admire the ornate frescoes, gilded carvings, and the large globes that decorate the space. Several reviews mention how the library looks so breathtaking that many hope to get photos of its interior. However, only one side can be photographed, so don’t forget to bring your camera or phone for some snapshots.

Travelers like Uen Ting, who remarked on the library’s beauty, often find it difficult to tear themselves away from the intricate details. The library’s ambiance is enhanced by the quiet reverence and the detailed ceiling frescoes, which depict mythological scenes and celestial bodies.

Meridian Hall: The Ancient Timekeeper

Next, the guide will take you to Meridian Hall, where you’ll see a collection of old instruments used to tell time. A small beam of sunlight shines through a hole in the wall at precisely noon, marking the moment for the exact time of high noon — a fascinating insight into how timekeeping used to be a science. According to one reviewer, the guide explained how the Meridian Hall was used for this purpose, adding a layer of practical history to the visual experience.

The stairs are broken into small, manageable chunks, and there are occasional stops to catch your breath and enjoy the views.

Once at the top, you’ll be treated to 360-degree vistas of Prague, including the Prague Castle and the city’s historic rooftops. Reviewers frequently mention how spectacular and worth-the-climb the views are.
