Verdict
Klementinum

Klementinum

A former Jesuit college complex housing a stunning baroque library hall and the Astronomical Tower, visited by guided tour.

The call

Worth it if you are watching the budget and you only have one day.

Why

  1. 01

    The baroque library hall and the climb up the Astronomical Tower for a 360° Old Town view are a quieter, more curated experience than the castle crowds.

  2. 02

    The honest catch: it's guided-tour-only on fixed slots, the tour is fairly brisk and you can't linger or photograph freely in the hall.
