Knock Castle, Sound of Sleat, Skye is a painting of the castle which lies on the northern point of Knock Bay in Sleat with a striking view over the Sound of Sleat to the hills of Knoydart on the mainland. In the nineteenth century it had long been a ruin, with high walls four feet thick, overgrown with ivy and haunted by ghosts. A perfect setting for Waller Paton, the artist, who enjoyed painting evening views of mountains and lochs on the west coast of Scotland.

Was the painting the Haywards' choice? Or, more probably, did Ursula inherit it from her family? The Barr Smiths were originally from Scotland, and a Scottish landscape hanging in their house in Adelaide, would have reminded them of their other 'home' thousands of miles away. But another, and more personal reason for owning the painting was the name itself, Knock Castle. George Elder, Ursula's great-uncle, having spent some six years in South Australia from 1849-1855, returned to live in Scotland and lived, until he died, at a Knock Castle further south at Largs in Ayrshire. Ursula's parents visited Knock Castle, and the painting now in the Carrick Hill collection, would have conjured up happy memories of that holiday.
