27 September 2025 (10:00 - 17:00) 28 September 2025 (10:00 - 17:55) PLEASE NOTE: Due to essential repairs, we will NOT be inviting visitors to the rooftop and Victorian telescope dome this year. There will be NO TOURS of these historical areas as they will be CLOSED. There are still lots of other areas to see on our site. As well as being an historic site, The Royal Observatory Edinburgh is a working observatory which houses more than 200 staff and students. It encompasses two organisations: The UK Astronomy Technology Centre (UK ATC) which includes the Higgs Centre for Innovation and the Institute for Astronomy (IfA). The UK ATC is part of UK Research and Innovation, and the IfA is part of the University of Edinburgh. Engineers at the UK ATC design extremely sensitive cameras and other instruments for many of the world’s best telescopes and for the big telescopes of the future. They are also finding innovative ways of using this technological expertise in fields outside of astronomy, including earth observation and medicine. The research of scientists at the IfA tackles many of the big questions in astronomy, including the search for life-bearing planets and studying the oldest and most distant objects in our universe. Last entry to site at 3.45pm.
