Urania Observatory

The Urania Observatory, the oldest public observatory in Vienna, is currently undergoing extensive renovation. A new telescope offering a fascinating view of the night sky over Vienna will be installed in autumn 2026. Despite the building works, the Urania Observatory will open its doors for the ‘ORF Long Night of Museums’. You can look forward to hands-on science shows, and stargazing from the roof terrace, weather permitting.

Please note that admission is every half hour and you will need a reservation card in addition to your ticket (available on site).
