Among them, the family home of historian Turtle Bunbury at Lisneva in Carlow.

So, Lisnevar House and Gardens were actually the last place he was working on.

He was working on them when he died in 1849.

He'd started them a couple of years earlier, in the epic year of 1847.

But he'd been based in Ireland pretty much from 1830 until 1849, until his death, where he was working on buildings and gardens, most famously, of course, the Italian gardens at Powerscourt, on the upper terrace at Powerscourt.

He, we assume he was commissioned to come to this environment because he'd been working on Carraglass Manor up in County Longford for the Lefroys, and the Lefroys were family members of, they were intermarried with the Lefroys, so I assume that's how it happened.

But he was also at Kilrudgery, where the 10th Earl of Meath lived.

But in 1843, Daniel Robertson is at Pariscourt, and it's here that his place in horticultural history was forged, for good and ill.
