The Fort at Fortstewart is a truly exceptional home, steeped in history and immersed in the stunning natural beauty of Donegal. With uninterrupted views over Lough Swilly and a rare combination of heritage, creativity and comfort, this is a property that captures both the imagination and the heart.
Set within 0.54 hectares of beautifully landscaped grounds, this extraordinary waterfront retreat enjoys direct access to one of Ireland’s most scenic and storied inlets.
At the centre of the property stands the original 1610 stone fort, built by Sir William Stewart following the Flight of the Earls. Now an atmospheric ruin, it provides a dramatic focal point, connecting the landscape with its layered past and lending an extraordinary sense of place to the estate.

The main residence, constructed in 2004, is a bright and beautifully proportioned two-bedroom home that sits just steps from the water’s edge. Designed to celebrate its surroundings, it is filled with natural light through tall picture windows, while soaring ceilings and an open flow create a calm and inviting atmosphere.
The living room is both refined and welcoming, with a stone-framed inset stove, bespoke bookshelves and sweeping views of the lough. The dining area opens through French doors onto a flagstone patio, offering the perfect spot for entertaining or simply soaking in the views. The galley-style kitchen is compact and well considered, with direct access to the rear garden and vegetable patch.
Both double bedrooms are spacious and serene, each with its own private ensuite and peaceful views, making the home equally suited for year-round living or luxury holiday escapes.
Positioned discreetly on the grounds is a second, contemporary building designed as an artist’s studio. Clad in cedar and measuring approximately 130 square metres, it is a stunning example of flexible, modern design. The ground floor features an open-plan kitchen, dining and living space, filled with natural light from roof-length skylights and three sets of French doors that frame the surrounding gardens and countryside.
Upstairs, a generous ensuite bedroom with expansive views provides an ideal retreat for guests, visiting creatives or extended family. The studio’s layout and location offer endless possibilities, whether as a creative workspace, a guesthouse or a private wellness retreat.
Donegal’s dramatic natural beauty surrounds you at every turn, from the beaches of Portsalon to the rugged Fanad Peninsula. Across the water, you can see the ruins of Burt Castle and the ancient hilltop ring fort of An Grianán of Aileach. At certain tides, monastic fish traps built in the 8th century become visible in the shallows, bearing silent witness to the centuries that have passed.
Despite its historic depth, the home is modern in every way that matters. With a BER rating of B3, underfloor heating, and thoughtfully selected materials, it delivers energy efficiency and contemporary comfort in a timeless setting.
