It is the oldest continuously operating planetarium worldwide.
The first-ever projection planetarium prototype was developed here by the Carl Zeiss company.
The building was constructed as a permanent home for the projection device that was first demonstrated at the Deutsches Museum in Munich.
The dome is made of a lightweight steel framework covered with perforated aluminum sheets, designed specifically for optimal acoustic and visual transmission.
It was one of the few buildings in Jena to survive World War II mostly intact, allowing it to maintain its historical continuity.
The planetarium's current technology includes a hybrid system that combines opto-mechanical star projection with modern digital laser projectors.
The Zeiss-Planetarium Jena is the oldest operating planetarium in the world, having opened its doors in 1926. It serves as a flagship site for Zeiss projection technology, utilizing a high-resolution laser projection system to display celestial movements across its 23-meter diameter dome. The facility integrates astronomical science with cultural programming, offering a diverse schedule of star shows, scientific lectures, and immersive fulldome music concerts. It is located in the city center of Jena, a hub long associated with the history of optics and precision engineering. Visitors experience a 360-degree digital visualization of the night sky, rendered with high-contrast, multi-channel sound systems. The institution remains a central site for scientific outreach and educational programming in Thuringia.
