Nestled on the wooded shore of Dunlewey Lough beneath the shadow of Mount Errigal, Dunlewey House dates to around 1830. With its distinctive castellated features and soft pink façade, it remains a striking landmark in the valley and is recognised as a protected historic structure.

In the 19th century it was home to the Russell family; Jane Russell, who commissioned the nearby Old Church of Dunlewey in memory of her husband James, was a notable figure in its history. In later years, the property passed to the Guinness family, who used it as a private holiday retreat.

Local folklore tells of the “Green Lady” — a spectral figure said to appear along the shoreline or gazing across the waters of the lough. Descriptions vary, but she is often portrayed as an elegant woman in a flowing green gown, silent and watchful. Whether she is a lingering spirit from the Russell era or a much older presence tied to the land, her legend is now inseparable from the story of Dunlewey House.
