Grassholme Observatory sighting

Private Hire

A haven for stargazers and explorers.

The Grassholme Observatory is a purpose-built visitor attraction in Teesdale.

It’s home to an array of sophisticated telescopes and instruments all installed to help you explore the universe around us. Situated on the banks of the Grassholme reservoir in County Durham it occupies a truly iconic location – with stunning scenery and big dark skies free from any light pollution.

The facility has a 20-seater heated classroom as well as its purpose-built observatory housing an array of powerful telescopes.

Under the directorship of Gary Fildes who founded and ran the Kielder observatory for over 17 years – It will be a night to remember – Gary’s experience is unrivalled in running astronomy centres and his infectious enthusiasm is contagious so beware!  

Here at Grassholme we believe in running a centre that caters to all the demands and diversity of our guests, from family astronomy to mathematics in astronomy and to instruments and imaging and back again. Whatever your astronomical preferences are we aim to satisfy demand. Which is why we also cater for private hire of the facility and Gary – Maybe for a birthday surprise or a corporate night out under the stars. Whatever your celebration the Grassholme observatory is ready and waiting for your group.

Demand for events is high so please book early to ensure your event is reserved.
