Knockaderry House, near Newcastle West in County Limerick, is an eighteenth-century country residence built around 1780. The detached, three-bay, two-storey house is distinguished by its balanced proportions, limestone eaves course and an attached architectural folly. Although now derelict, much of the original structure and historic fabric survives, allowing the building to retain a strong sense of its former character. The house is also remembered as the birthplace of pioneering Irish aviator Sophie Peirce-Evans. Set within the rural Limerick landscape, Knockaderry House remains an important reminder of the county’s architectural, social and aviation heritage for future generations to study and appreciate.
