The sundials working group of the Czech Astronomical Society in Hradec Králové organized a short study tour to Poland in June 2016 with a special emphasis on seeing sundials. This report is provided by Hohumil Landsman:

"The first stop was the Muzeum im. Przypkowskich, the world famous museum that began as the clock collection of the Przypkowski family. It is situated in the town square of Jędrzejów. As well as various fixed and portable sundials, the museum showed devices for the construction of sundials and several old books on astronomy and gnomonics."

"From there we visited the Planetarium and Observatory of Youth in Niepołomice. Among other things, there were commentaries available for blind visitors for whom the spoken word is a principal source of information.  Another interesting stop was the Silesian Planetarium and Astronomical Observatory of Nicolaus Copernicus in Chorzów.  In the courtyard of the planetarium there is a large sundial showing local solar time, and in the basement we found a seismological station containing two early 20th-century seismographs as well as their more modern equivalents. A meteorological station forms part of the same complex of buildings. As an additional diversion, we also visited the salt mines in Wieliczka."
