CoSA – Center of Science Activities is Universalmuseum Joanneum’s hands-on science centre at Joanneumsviertel 1 in the Joanneumsviertel, in Graz’s central Innere Stadt, Austria. Opened in 2019, it replaces the conventional museum model with experiments, digital installations and participation: visitors come to test ideas about science, technology, health and society rather than simply look at objects in cases. Its 13 experience spaces, designed especially for curious teens and adults but open to all ages, make it one of Graz’s most engaging indoor stops.
What to Expect at CoSA – Center of Science Activities
CoSA is arranged as an interactive route through large, darkened exhibition rooms within the historic Joanneumsviertel complex. At the entrance, visitors create a personal digital avatar; this becomes a thread through the visit, prompting choices and questions at selected stations. The content moves across natural science and technology into the human questions behind them: how people perceive the world, make decisions, use data and live with scientific change. Many installations ask for a response, experiment or comparison rather than offering a fixed answer.
Allow time for the physics, chemistry and life-science challenges, as well as the installations on digital technology, health and society. The CoSA MakerSpace is the practical counterpoint to the exhibition, providing guided formats where visitors can make, test and develop ideas with tools and materials. Workshops and special programmes change, so check the official calendar before travelling. The atmosphere is more laboratory than gallery: touch screens, sound, moving mechanisms and task-based exhibits reward visitors who slow down and try things for themselves.
- Digital avatar journey: Create an avatar at the start and encounter questions tailored to your choices as you explore.
- 13 experience spaces: A substantial, multi-topic route linking natural science, technology, health and social questions.
- Hands-on experiment stations: Test principles through direct action instead of reading labels beside a collection.

Visiting Tips, Getting There & Nearby Pairings
Book through the official CoSA ticket page before arrival, even though entry is free; timed tickets keep capacity manageable. Tuesday to Friday mornings outside Austrian school holidays are the calmest periods for lingering at popular stations. Weekend afternoons tend to attract families and local visitors. Start early if you want to combine CoSA with another Joanneum museum on the same day, and bring a light layer: the exhibition is indoors, but Graz’s old-town streets between stops are exposed to the weather.
From Hauptplatz/Congress, walk south-east along Herrengasse and cut through the old town toward the Joanneumsviertel; Jakominiplatz is also an easy walk and the city’s main tram interchange. The museum has step-free access, lifts connecting levels and accessible sanitary facilities, making it suitable for wheelchair users and strollers; ask the front desk for the most direct accessible route through the installations. Pair a visit with the Styrian Armoury, roughly five minutes away, or the exhibitions of the Neue Galerie Graz in the same Joanneumsviertel. Hauptplatz, the Landhaus courtyard and cafés around Herrengasse and Schmiedgasse are all within a 5–15 minute walk.
