Stone Trough History - Most troughs were built for watering stock and are found both within and along the edges of fields. They can also be found in the enclosures attached to field barns where they held water for over-wintering cattle. Many troughs are set into field walls so that they can serve stock in two fields; these often have a sandstone divider or bars across the middle, as with the trough pictured.
A rather striking water feature beautifully lit. One wonders what's going on in the rest of the garden - black limestone paving/Ophiopogon planiscarpus 'Nigrescens'/Astelia chathamica 'Silver Spear'? ... the creative juices are flowing!
