The impressive sandstone building stands proud atop Balgay Hill within a wood on Dundee city centre’s outskirts. It boasts fantastic views over the River Tay from its dome and balcony areas.
Join the experienced and friendly staff as they give you a guided tour of fascinating objects seen through their range of telescopes.
Admission is free, except for selected events, and there is no need to book a visit; simply drop in! An excellent experience for everyone!
