The Irish Yew Walk at Hillsborough Castle, County Down has a south-facing vista that concludes in Lady Alice’s Temple. The walk was laid out in the late 1870s by Colonel Arthur Hill who was then living in the house, although it belonged to his nephew, the sixth Marquess of Downshire. Col. Hill is also believed to have erected the temple on the site of a former summer house in honour of his sister Lady Alice Hill who had married Thomas Taylour, Earl of Bective in 1867. The ten Ionic columns supporting a masonry entablature & copper-clad masonry dome are made of cast-iron.
