What is recorded here

Howth Castle stands as a layered fortress of memory, its oldest wing dating to 1738 while later additions stretched across two centuries. The domed belvedere still catches ocean light, overlooking waters where ships have sailed since antiquity. Each architectural change marks another family's desire to possess and transform the headland, creating a building that refuses simple categorisation.

Attached ten-bay single-storey wing with half dormer attic, built 1738, on an L-shaped plan. Three-bay single-storey return with half dormer attic to west, having domed belvedere to apex. Façade and openings remodelled c.1840. Two-bay two-storey return added to west c.1910. Conservatory added to return c.1990.
