Discover more about Klementinum

The Klementinum is one of the largest building complexes in Europe, second only to Prague Castle in size within the city. Its history dates back to the 11th century with a chapel dedicated to Saint Clement. Over the centuries, it evolved from a Dominican monastery to a Jesuit college in 1556, eventually becoming a university in 1622. The main construction phase occurred between 1578 and 1726, resulting in the magnificent Baroque architecture seen today. The complex boasts a rich intellectual history, having been a center for education, science, and culture for centuries. The Jesuits established a library that became one of the most important collections of books and literary material in Europe. The Klementinum also housed an astronomical observatory, which began meteorological measurements in 1775, marking the longest uninterrupted climate observation record in the Czech lands. Today, visitors can explore the Klementinum through guided tours. Highlights include the Baroque Library Hall, with its stunning frescoes, antique globes, and rare books. The Astronomical Tower offers panoramic views of Prague and houses historical measuring instruments. The Meridian Hall features original astronomical instruments used to determine noon. The Mirror Chapel, with its mirror-decorated ceiling, hosts classical music concerts.
