The Mull of Galloway Lighthouse Exhibition is housed in the former fuel store, workshop and engine room to the right of the Lighthouse.

The Exhibition opened its doors for the first time on Good Friday 2009 after much hard work by a team of volunteers from South Rhins Community Development Trust.

In pride of place is the Fresnel Lens from McArthur’s Head Lighthouse, which was upgraded to an automatic light in 1969. The lens has been loaned to the exhibition by the Museum of Scottish Lighthouses in Fraserburgh. This museum has been instrumental in supplying on loan a range of artefacts, many original to the Mull of Galloway, as well as offering advice and expertise.

The Mull of Galloway Trust now operates the exhibition and tower tours and they are responsible for the refurbishment of the engines and foghorn.
