Silesian Planetarium
planetarium in Chorzów, Poland
The Silesian Planetarium also Silesian Planetarium and Astronomical Observatory (Polish: Planetarium Śląskie Polish: Śląskie Planetarium i Obserwatorium Astronomiczne) is the largest and oldest planetarium in Poland. It was founded on 4 December 1955 to commemorate Nicolaus Copernicus. It is located in the Silesian Park, on the boundary between the Katowice and Chorzów cities in the Metropolis GZM.
Facilities
The Planetarium's 23-meter dome can seat four hundred spectators viewing projections of the sky from both analogue and digital planetarium projectors. It hosts regular public shows on astronomical topics as well as a variety of other events. In 2011 it hosted the fifth International Olympiad on Astronomy and Astrophysics.
The Planetarium's sister astronomical observatory is equipped with a 300-mm diameter refracting telescope (the largest refractor in use in Poland) and a number of smaller instruments. On cloudless days, visitors can view live images of the Sun and, after dusk, a range of celestial objects at a magnification of up to 750 times.
The observatory conducts research on comets and minor planets. The Planetarium has an astronomical library of some 10,000 volumes and, in the courtyard, a large sundial. The corridors host astronomy-related exhibits.

Why this record matters
The phrase “planetarium in Chorzów, Poland” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jan 21, 2025. The linked authority identifier is Q833520. Authority coordinates are 50.291, 18.992. 2 of 3 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1955 and 2011.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
