North Lighthouse conservation project completed after more than a decade of restoration
The long-running conservation programme at the North Lighthouse in Mornington has now been officially completed, bringing to a close works that began in 2016 to safeguard the historic structure for the future.
The project was undertaken by Drogheda Port Company under the supervision of conservation architect Fergal McGirl and supported through the Built Heritage Investment Scheme administered by Meath County Council.
The Drogheda North Lighthouse is one of three related lighthouses constructed and commissioned in 1842 by the Drogheda Harbour Commissioners to guide vessels safely into the Port of Drogheda. The structures served as both day marks and lighted night marks, playing a vital role in maritime navigation.
Architecturally, the lighthouse makes a significant contribution to the surrounding landscape. It forms part of a distinctive group alongside the related lighthouses in the area and other sea safety structures including beacons and the former lifeboat house. The building retains many of its original materials and features.
Restoration works were carefully phased, with skilled craftsmen addressing the most urgent structural issues first. Initial interventions focused on stabilising the historic battery array. Attention then turned to the lantern housing, where long-term water ingress had caused substantial deterioration.
The works included replacing the lantern porch roof, reinstating decayed timbers with like-for-like replacements, and restoring the lantern lead roof in line with original detailing. These measures ensured the weatherproofing and structural integrity of the upper section of the lighthouse.
The most extensive and technically demanding phase involved the wrought iron cross braced tower structure. This was returned to its original condition, significantly enhancing its resilience and long-term stability. This stage represented the largest single investment of time and labour within the project.
Despite interruptions caused by the COVID 19 pandemic, all phases of the programme have now been completed. The restoration reflects a conservation led approach that prioritised safety, heritage integrity and sustainability.
The project highlights the importance of continued investment in the region’s built heritage and demonstrates collaboration between Drogheda Port Company, the project team, specialist contractors and Meath County Council through the Built Heritage Investment Scheme.
Today, the North Lighthouse stands structurally secure and weather tight, with its architectural character preserved and its lifespan extended. Ongoing maintenance and monitoring will remain essential, particularly given its exposed coastal location.
A similar restoration project is due to begin on the East Lighthouse later this year.
