Mills Observatory

Mills Observatory is an astronomical facility on Balgay Hill housing a Victorian-era refracting telescope inside a sandstone dome structure. The building overlooks the River Tay valley and includes exhibition spaces and a planetarium for learning about space.

The observatory opened in 1935 following a bequest from linen manufacturer John Mills, who wished to advance public astronomy. It was the first purpose-built public astronomical facility of its kind in England.

The site functions as a gathering place for those interested in astronomy, offering programs and meetings for amateur observers and learners. Visitors find a welcoming space to explore the night sky together and deepen their understanding of what lies above.

Access to the site involves walking up the hill on footpaths, so visitors should expect uneven terrain. Observations work best on clear, cloudless nights when the sky is dark enough for good visibility.

The facility was funded by a wealthy private individual whose name remains attached to the building to this day. This connection between benefactor and place stands out in Scottish history.
