Overview
Glenmona House stands on a windswept promontory just north of the village of Cushendun, overlooking the Atlantic coast in County Antrim. Set within a dense stand of mature pine trees, the roofless Neo-Georgian mansion is best known for its dignified front portico and a row of stately Tuscan columns. Though the building is no longer inhabited and the interior is largely inaccessible, the structure remains one of the most striking architectural landmarks on the northern coast. Its weathered stone and ironwork contrast sharply with the surrounding woodland and the open sea beyond, making it a quiet draw for photographers, history enthusiasts, and walkers exploring the area.
History & Architecture
The house was commissioned in the early 1920s by Ronald John McNeill, later known as Lord Cushendun. He hired Clough Williams-Ellis, an architect who would later achieve international fame for designing the whimsical Italianate village of Portmeirion in North Wales. For Glenmona, Williams-Ellis adopted a more restrained Neo-Georgian style, prioritising symmetry, classical proportion, and a strong connection to the landscape. Completed in 1923, the house was intended to serve as the social and architectural anchor for a newly planned seaside settlement that Lord Cushendun developed for his wife, Maud. The wider village features whitewashed cottages designed to evoke a Cornish coastal feel, a deliberate departure from typical Irish seaside architecture of the period.
Glenmona House was originally equipped with period features including a formal garden, a stone fountain, and a sundial. As the decades passed, the property fell out of residential use and gradually succumbed to the elements. By the early 21st century, it had become an abandoned shell, drawing interest from urban explorers and documentary filmmakers. Today, it is protected as a listed building and falls within the National Trust conservation area that encompasses much of the Cushendun coastline.
What to See & Do
Visiting Glenmona House is as much about the setting as it is about the building itself. The site offers a handful of specific experiences for visitors:
- Architectural Details – The front portico remains remarkably intact. The Tuscan columns, rusted iron balustrades, and the faint outlines of original sash windows provide a clear picture of early-20th-century design principles. The way the structure catches morning light or stands silhouetted against winter skies makes it a frequent subject for landscape photography.
- Wildlife Watching – The pine woodland surrounding the house is actively managed by the Glens Red Squirrel Group, which has established an activity playground and monitoring stations nearby. Early morning and late afternoon offer the best chances to spot the region’s native red squirrels moving through the canopy.
- Coastal Views – The house faces north, deliberately oriented to frame the Atlantic horizon. From the front steps, you can look out across the water toward the rugged coastline of the Antrim Glens. On clear days, the view extends along the shoreline to the distant headlands.
- Garden Remnants – Wander carefully through the lower grounds to find the stone base of the original fountain and a weathered sundial, both partially reclaimed by ferns and undergrowth. These features hint at the formal landscaping that once surrounded the estate.
Conservation & Restoration
The National Trust now oversees the long-term preservation of the site, shifting the focus from abandonment to careful stabilisation. A structural survey by specialist firm Stronghold Preservation identified issues with penetrating damp and failing window lintels. Conservators addressed these by reinforcing the masonry with stainless-steel helical stitching bars, a technique that strengthens the walls without altering the historic fabric.
Recent years have seen increased ground-level work. The BBC’s Gardeners’ Corner highlighted a 2023 restoration effort led by National Trust gardener Una Quinn, which focused on clearing invasive overgrowth, improving safe access to the main footpath, and gradually uncovering the historic garden features. The goal is not to rebuild the house as a residence, but to arrest its decay and maintain it as a stable, publicly viewable ruin that reflects both its architectural heritage and its natural setting.
Practical Information & Safety
Glenmona House operates as an unstaffed historic site with no formal opening hours or admission charge. It is accessible from Glendun Road, where limited roadside parking is available. A footpath leads through the pine woodland to the front of the house. For a more extensive visit, many travellers park at the National Trust car park near the Cushendun beach and walk the short distance inland.
Safety & Access Guidelines
- The building is structurally unstable. Do not enter the interior or climb on any masonry.
- Wear sturdy, closed-toe footwear. The ground around the ruin is uneven, with loose stones and overgrown roots.
- If you plan to photograph close to the structure, bring gloves and a dust mask to protect against decaying timber and masonry dust.
- Keep dogs on a lead, as the area is used for wildlife monitoring and the grounds contain fragile undergrowth.
The house is best visited as part of a broader trip to the area. A short walk south leads to the 3.4-mile white-sand beach and the sandstone church that now operates as a community arts centre. For longer routes, the Glens Great Grassland Trail loops through nearby meadowland and coastal paths, while the wider Antrim Coast and Glens offers numerous scenic drives and cliff walks. Check tide times before visiting the beach, and allow extra time in summer when the pine canopy is densest, as it can partially obscure the house from the road.
