Thousands of people had gathered to watch Durdle Door illuminate as part of a nationwide art project. They gathered on the cliff-top and on the beach to watch as the iconic arch played host to the display. It was part of an ambitious plan to simultaneously light up UNESCO World Heritage sites across the UK and Ireland ? an idea developed by the Society of Light and the Chartered Institution of Building Services Engineers. Bournemouth-based designers from Michael Grubb Studio used a man rowing in a boat under the Jurassic Coast landmark, accompanied with the use of various tricks, in a bid to create a scene reminiscent of impressionist art.
