Renaissance astronomy in Kepler's Prague: Czech Republic
14 September 2025 - 6 days for £2,169 per person.
Discover the giant legacy of the Renaissance period astronomers Johannes Kepler and Tycho Brahe in Prague, the city of a hundred spires, where astronomy, maths, music and art connect. Accompanied throughout by astronomer and historian Martin Griffiths, journey to the heart of early science, exploring Prague’s medieval marvels and walking the streets as Kepler and Brahe did whilst Martin and the local guides share tails of Renaissance history.
Kepler was one of the world’s most influential astronomers whose work on optics and the laws of planetary motion would influence the ground-breaking research of Galileo and Newton after him. He spent some of his most important years working with Tycho Brahe in Prague, whom he replaced in 1601 as imperial mathematician and advisor to Holy Roman Emperor Rudolph II. Prague in the 17th century was a melting pot of international artists, scientists and thinkers, attracted by the tolerant political climate.
Your tour includes the world’s oldest astronomical clock, Prague Castle and the Klementinum astronomical tower, then enjoy stargazing at the Stefanik Observatory. You will also explore the historically fascinating towns of Nelahozeves and Kutna Hora, a UNESCO World Heritage site. Martin will give four evening lectures and also lead the stargazing session.
Senior lecturer in space science at the University of South Wales, Martin Griffiths will accompany you throughout. Martin will give lectures and walking seminars throughout.
In partnership with Kirker Holidays.

There will also be a visit to the National Technical Museum including its fascinating astronomical section and Kepler exhibit and to the Tyn Church where Kepler’s mentor Tycho Brahe is buried.
Martin will accompany the group throughout the day and give a second talk on Kepler and the three laws of planetary motion that he developed. Then onto dinner in a local restaurant.
DAY 3: THE KLEMENTINUM AND BENATKY CASTLE AND THE STEFANIK OBSERVATORY
In the morning, you will journey outside the city limits to Benatky Castle where Tycho Brahe lived from August 1599 to June 1600. This magnificently decorated Renaissance and Baroque palace was not only the site of Brahe’s observatory but was also home to the Czech composer BedÅ™ich Smetana.
In the afternoon, you will return to the city and continue exploring the scientific heritage of Prague with a private guided tour of the Klementinum led by Martin. Formerly a university, the significance and importance of the Klementinum's astronomical tower, Meridian hall and baroque library to science and astronomy cannot be understated. The Meridian hall was once used to determine when noon occurred each day, and both Kepler and Brahe developed their ideas here.
In the evening, you will visit the Stefanik Observatory, where under Martin’s guidance and advice from the expert observatory team, you can look beyond the boundaries of the solar system and observe selected stars, nebulae, clusters and galaxies.
DAY 4: THE CASTLE DISTRICT AND NELAHOZEVES
