FREE ENTRY / Rundetaarn - Open Call for Exhibitions

The year 2026 marks the 350th anniversary of Ole Rømer’s groundbreaking discovery of the speed of light, and the theme for the exhibitions will therefore be “LIGHT” in all its facets—literal or metaphorical.

“LIGHT” will be the overarching theme that the exhibition series must reflect. It is a requirement that all exhibitions created for the Library Hall in 2026 address or interpret this theme.

Exhibitions may be based on scientific, historical, or astronomical aspects, but literary, philosophical, and religious approaches are also welcome. The theme can also be related to contemporary and future issues and research.
