Dennis Head Old Beacon is a ruined lighthouse on the island of North Ronaldsay, Orkney, Scotland. The beacon and keepers' houses are protected as a scheduled monument. It is one of the earliest surviving purpose-built lighthouse towers in Scotland.{{Historic Environment Scotland|num=SM6596|desc=Dennis Head, Old Beacon, North Ronaldsay|access-date=30 June 2025}}
History
Calls for a lighthouse to be built on the island began in 1740 after the Swedish East Indiaman ship Svecia carrying cargo worth around £200,000 sank off the coast of North Ronaldsay. As a result of the sinking, the first survey of British waters was carried out by hydrographer Murdoch Mackenzie. However, a lighthouse was not approved on the island until the late 18th-century when tensions with France caused trouble for ships crossing the English Channel. Permission was then granted by the Commissioners of Northern Lighthouses for a lighthouse at Dennis Head to be built.{{cite news|last1=Gourlay |first1=Kath |title=Race to save an Orkney landmark |url=http://heritage.scotsman.com/places.cfm?id=1132192006 |work=The Scotsman |access-date=30 June 2025 |archive-url=https://web.archive.org/web/20070819235822/http://heritage.scotsman.com/places.cfm?id=1132192006 |archive-date=19 August 2007 |date=4 August 2006 |url-status=dead}}
Construction on the {{convert|70|ft|adj=on}} tower began in 1788 under the supervision of Thomas Smith assisted by his stepson Robert Stevenson to designs by Ezekiel Walker.{{cite web |last=Olsen |first=Victoria |date=24 August 2006 |title=Beacon places North Ronaldsay in the national spotlight|url=http://www.orkneytoday.co.uk/news_item.asp?newsItem=321|website=Orkney Today |archive-url=https://web.archive.org/web/20070928000236/http://www.orkneytoday.co.uk/news_item.asp?newsItem=321|archive-date=28 September 2007|access-date=30 June 2025|url-status=dead}} They used materials and workers from Leith. It was completed the following year and was first lit on 10 October 1789. The total cost of construction was £199 12s 6d. It was to be the first of many island lighthouses for Smith (he had previously worked on the lights at Kinnaird Head and Mull of Kintyre).{{cite web |title=North Ronaldsay |url=https://www.nlb.org.uk/lighthouses/north-ronaldsay/ |website=National Lighthouse Board |access-date=30 June 2025}}
Its lighting system, although advanced for its time, consisting of a cluster of oil-burning lamps and reflectors was not very effective, often being mistaken for the mast-head of another ship by mariners. In 1809, with the construction of other nearby lighthouses, it was decided that the lighthouse was no longer required, and the light was extinguished.
Another lighthouse, North Ronaldsay Lighthouse, was built on the island in 1852.{{cite web |title=North Ronaldsay Lighthouse |url=https://www.orkney.com/listings/north-ronaldsay-lighthouse |website=Orkney.com |access-date=30 June 2025}}

Architecture
The majority of the lighthouse was constructed using local undressed stone, apart from the corbels and a spiral staircase, the latter of which collapsed in the lighthouse resulting in some projecting stubs from the walls. Two lightkeepers houses was also built beside the western side of tower. However, the houses are currently roofless.{{cite book |last1=Findlay |first1=Alexander George |title=A Sailing Directory for the Navigation of the North Sea, Describing the Eastern Coasts of Great Britain, from the Downs to Shetland Volume 1 |date=1883 |publisher=Richard Holmes Laurie |page=214 |url=https://www.google.co.uk/books/edition/A_Sailing_Directory_for_the_Navigation_o/CGCTPNV_LjIC?hl=en&gbpv=0}}
After it was extinguished, the light at the top of the tower was replaced with a large masonry ball {{convert|8|ft|adj=on}} in diameter.{{cite book |title=Sailing directions for the North Sea.
