Forming a distinctive part of an estate, a demesne encompasses the principal residence of the landholder and an area of surrounding lands retained exclusively for the landholder’s use. As Irish landholders transitioned away from fortified houses within defensive bawns over the course of the second half of the seventeenth century and first decades of the eighteenth, the nature of Irish demesnes altered. Enclosure walls were removed, new formal gardens laid out, walks and water features developed, and trees planted within demesnes and around their boundaries to create vistas of and from new or enlarged country houses.
All of these trends are clearly discernible in this large drawing produced by the otherwise unknown ‘Surveyor of Lands & Valuer of Estates’ John Hill, recording proposed alterations to Howth Castle Demesne by the also unknown Thomas Simpson. The absence from the drawing of the north and east wings of the castle, and the inclusion of a ‘Proposed Enlargement’ on the site of what would become the west wing from c. 1740, indicate that the drawing was made before alterations and additions carried out for William St Lawrence, 14th Baron Howth.
This drawing was in a very poor condition when it was donated the IAA by Julian Gaisford St Lawrence in 2024. Torn, creased, dirty, and with substantial losses, it has been carefully and meticulously restored by paper conservator Liz D’Arcy in a project made possible by funds bequeathed to the IAA for this very purpose by the late Homan Potterton. Many of the features delineated in the drawing were identifiable on OS maps into the twentieth century and, despite the later transformation of much of the Demesne for golf use, some are identifiable on the ground to this day.
