Overview
Lough Rynn has the largest privately owned walled gardens in Ireland, and they’re free to walk – reason enough to pull off the road even if you’re not among the guests staying in the castle hotel behind them. The gardens sit on a 300-acre peninsula between Lough Rynn and Lough Errill, four kilometres north of Mohill in County Leitrim.
The house itself is a restored Victorian estate: a baronial hall, oak-panelled rooms, a John McGahern Library named for Leitrim’s greatest novelist, and the two-AA-Rosette Sandstone Restaurant. It runs as a self-contained hotel for couples, weddings and corporate groups, so the grounds are busiest – and occasionally closed for private events – at weekends. Come midweek if you want them quiet.
History & heritage
The land was the ancestral territory of the Mac Raghnaill clan, recorded in the Annals of Loch Cé as early as 1247. A medieval crannóg and a square castle with rounded corners once guarded the shore; the castle’s ruins still stand about 500 metres from the present house. In the early 17th century the estate passed to the English Crofton family, and by 1750 to the Clements, whose line produced the 3rd Earl of Leitrim – one of the most hated landlords in Irish history, shot dead in County Donegal in 1878.
Colonel Henry Theophilus Clements enlarged the house in 1889, adding the Baronial Hall, an ornate inglenook fireplace and oak-panelled rooms. The property stood largely empty after the 1970s until an Irish-American investor bought it in 1990. The Hanly family took it on in 2001 and, after a full restoration, reopened it as a luxury hotel in September 2006.
The gardens & grounds
The estate’s grounds run from ancient history to formal horticulture:
- Terraced walled gardens – three tiers of formal beds, box hedging and a rose garden, first laid out between 1855 and 1860 and reopened to the public on 5 August 2008 as the largest privately owned walled gardens in Ireland. They supply much of the produce for the hotel kitchen, and are open daily from 09:00 to 17:00, with guided tours on Tuesdays to Thursdays at 11:00.
- Druid’s Hill – a four-hundred-year-old oak and a Bronze Age tomb known as Cloch an Draoi.
- Red Bridge and Blue Bridge – crossing points over the Rynn River that frame the classic views of the castle.
- Crannóg site – a short walk leads to the remains of the medieval lake-dwelling, a quiet spot to take in the area’s early history.
- Rockery and wishing chair – a lakeside nook for a peaceful pause.
Accommodation & dining
The castle offers a range of lodging to suit different travel styles:
- Luxury bedrooms & suites – en-suite rooms with under-floor heating, Wi-Fi, air-conditioning and period décor.
- Medieval-themed stables – 16 rooms with stone walls and period-style furnishings for a more rustic stay.
- Self-catering lodges – three-bedroom houses with private entrances and kitchens, sleeping up to five.
Dining leans on the estate itself. The Sandstone Restaurant holds two AA Rosettes and takes ingredients straight from the walled garden. There’s afternoon tea in the drawing rooms with lake views, and cocktails in the Dungeon Bar, which keeps the wood-panelled feel of the original house. There’s no gym or leisure centre at present, though a wellness centre and spa are in development.
Activities & experiences
Beyond the castle walls, the surrounding landscape offers plenty to explore:
- Walking & nature trails – marked routes wind through woodland, wetland and along the lake shore.
- Water sports – kayaking and fishing run from the estate’s boathouse on Lough Rynn.
- Cycling & horse-riding – local providers operate from nearby Mohill, with routes connecting to the wider Shannon-Erne Waterway trails.
- Distillery visits – the estate works with the Shed Distillery in Drumshanbo, a short drive away, for guided tours and tastings.
Weddings & events
The function rooms can host weddings for up to 300 guests, along with corporate conferences and private celebrations. An adjoining ballroom and a dedicated conference suite provide flexible space, and the lakeside setting supplies the backdrop for photographs. Planning approvals are in place for a significant expansion that will add rooms and wellness facilities while keeping the historic core intact.
