Outdoor art installations are incredibly inspirational – not only because they showcase an artist’s expression of creativity, but they are designed to sit within a landscape giving the ideas more context than an isolated piece of artwork. Land artist Richard Long’s Cornwall Slate Line was placed at Chatsworth in 2010. Like much of his work, it’s directly translatable to garden design. The same installation is displayed in both a gallery and garden setting, showing the versatility of the piece. It’s great to see the textures of the stone when both wet and dry – something that is often overlooked at early landscape design
