Open Call for Exhibitions
The Round Tower announces an annual Open Call for exhibitions in the Library Hall, inviting artists, designers, architects, communicators, and researchers to apply for an exhibition period.
The Round Tower was built to elevate human insight and perspective. As a unique historical and architectural landmark with approximately 650.000 annual visitors, it is one of Denmark’s most visited cultural institutions, and home to the oldest observatory building in Europe.
In the 900 m2 Library Hall, located halfway up the tower above the Trinitatis Church, exhibitions, concerts, and events are held. The cultural program of the Library Hall is meant to convey the narrative of the entire building complex’s world of history, church, and astronomy, brought to life through contemporary and relevant content in art, science, adventure, and architecture.
Since 1987, when the Library Hall opened in its current form, the Round Tower has been able to present a varied program consisting of changing exhibitions and cultural events.
The Library Hall has hosted more than 270 exhibitions.
