Having an interest in Space and the science, it seemed silly not see one of Prague’s biggest attractions in both of these subjects, the astronomical tower found inside the  Clementinum.

The Clementinum (aka ‘Klementinum’) in Prague is a big historic complex with roots dating back to the 11th century. Originally established as a chapel dedicated to Saint Clement (hence the name!), the site grew over the centuries to become one of the largest building complexes in Europe. The Clementinum is renowned not only for its architectural beauty but also for its rich history in education, science, and culture.

One of the most significant parts of the Clementinum is its Astronomical Tower, which stands as a symbol of Prague's long-standing contribution to astronomy. The tower was completed in 1722 and has played a crucial role in scientific observations ever since. Standing at 68 metres tall (bigger than the Leaning Tower of Pisa and Arc de Triomphe in Paris), it offers incredible panoramic views of the city, making it a popular attraction for visitors that you have to book a tour as part of a group.

 The Astronomical Tower was once part of the Jesuit College within the Clementinum, and it became a centre for astronomical studies in the 18th century. The tower was equipped with various instruments for celestial observations, including the famous Meridian Room, where noon was determined daily by measuring the position of the sun. This measurement was so precise that it was used to set the official time in Prague, and a time ball was dropped from the tower each day to signal noon to the city, which you can still see today when the Astronomical clock chimes.

The tower also houses a fascinating collection of historical astronomical instruments, including telescopes and globes, showcasing the advancements in astronomy over the centuries. Among the notable figures associated with the Clementinum is the astronomer and Jesuit priest Joseph Stepling, who made significant contributions to the field during the 18th century.

Today, the Clementinum and its Astronomical Tower remain a testament to Prague's intellectual heritage. Visitors can tour the complex, explore its beautiful Baroque library, and climb the Astronomical Tower to enjoy breathtaking views and a glimpse into the history of astronomy. The Clementinum continues to be a place where the past and present of science and culture meet, offering an enriching experience for all who visit.
