Welcome to Mills Observatory

Mills Observatory

Britain’s first purpose-built public observatory enjoys a magnificent woodland setting on the summit of Balgay Hill. Watch stars and planets through our telescopes, or admire the scenery with some spectacular treetop vistas across the silvery Tay.

With fascinating space exploration and astronomical displays, planetarium shows and a fully computerised telescope that can detect 30,000 objects in the sky, there’s so much to see, do and learn! Our friendly staff are on hand to help and advise.
