The Baroque Library Hall, completed in 1722, has never lent out a single one of its 20,000 volumes. The Klementinum grew from a Jesuit college into the second-largest enclosed complex in Prague, its courtyards stitched together over two centuries beside the Old Town's narrow lanes.
Meteorological records have been taken here without interruption since 1775, one of the longest continuous series in central Europe. The Astronomical Tower, the Meridian Hall, and the frescoed library make the klementinum tour a passage through the history of measurement itself. Today a klementinum baroque library tour and a klementinum astronomical tower tour share the same 380 CZK ticket, and a clementinum guided tour prague visitors trust threads all three together under one Jesuit roof, with the Mirror Chapel's acoustics drawing concert audiences after dark.
"Twenty thousand volumes, and not one has ever left the room."
A step-by-step walkthrough of Klementinum tickets — what you'll see, how long each stage takes, and the details that matter.
You step off Mariánské náměstí at 09:15, inside the best arrival window, where first morning tours carry a 50% early-bird discount and the smallest crowds.
Your guide gathers the group, and you cross a quiet courtyard toward the Baroque Library Hall, where you pause beneath frescoed ceilings and gilded globes you cannot touch.
You move to the Meridian Hall, then begin the climb — 172 steps in all — up the Astronomical Tower. You stop twice to catch your breath on the spiral. At the top, you lean into the railing and trace the spires of the Old Town, the river bending past the Charles Bridge. On a guided klementinum skip the line slot, the site rewards an early start; you descend before the midday queues form below.
Arrive at Mariánské náměstí 190/5 no later than 15 minutes before your tour slot. Collect or exchange your voucher at the ticket office beneath the Astronomical Tower. The meeting point is in the central courtyard next to the Mirror Chapel.
The guide leads the group to the viewing platform overlooking the hall. Observe the ceiling frescoes, two antique celestial globes, and the towering wooden bookshelves holding manuscripts dating back centuries. Photography is permitted without flash.
On the second floor of the Astronomical Tower, the Meridian Hall displays period astronomical instruments used to determine solar noon for timekeeping across Bohemia. A marble meridian line is set into the floor.
Climb the remaining steps of the 172-step staircase to reach the open-air gallery at the top of the Astronomical Tower. Panoramic views extend over the Vltava River, Charles Bridge, and Prague Castle.
The landmarks, rooms, and views travelers on Klementinum tours remember — all visible on a single visit.
One of the few Jesuit libraries in Europe to survive intact, the hall holds around 20,000 volumes dating from the 16th to 18th centuries beneath a continuous illusionistic ceiling fresco painted by Jan Hiebl in 1727.
Positioned on the second floor of the Astronomical Tower, this room contains original 18th-century astronomical instruments and a marble meridian line embedded in the floor, used for centuries to determine solar noon across Bohemia.
At the summit of the tower, an open-air walkway offers a 360-degree panorama taking in Prague Castle, the Vltava River, and the red-tiled rooftops of Old Town; the tower has hosted Europe's longest continuous meteorological record, running unbroken since 1775.
Built between 1724 and 1726, the chapel features walls entirely lined with mirrors and houses two original Baroque organs; W. A. Mozart is documented to have performed on one of these organs during his Prague visits in the 1780s.
The five interconnected courtyards contain the largest assembly of sundials in the Czech Republic, with multiple instruments installed on the exterior walls of the former Jesuit college — visitors can explore these freely without a ticket.
