At the start of the 18th century, Peter Aylward, who came from Aylwardstown at the southern boundaries of County Kilkenny, married Elizabeth Butler. Her father, Sir Richard Butler, owned property at Paulstown further north in the county and the young couple settled here in an old tower house which they then modernised and extended. The new range had a recessed centre with projecting bays on either side, one of which was the original tower house.  This building appears to have survived unchanged for a century until some date in the 1820s/30s when a further single bay extension was added and the whole exterior crenellated, so that the house was thereafter called Shankill Castle; this work has been attributed to local architect William Robertson. In 1861, a conservatory designed by Sir Joseph Paxton and opening off the drawing room was added, but then taken down 100 years later. What does survive is another conservatory on stilts at the back of the building, accessed from a return on the main staircase. Shankill Castle remained home to Peter Aylward’s descendants until 1991 when it was sold; the property has since been owned by historian Geoffrey Cope and his artist wife Elizabeth.
