As the centerpiece of the exhibition, 'Lightscape: James Turrell at Houghton', the 7th Marquess of Cholomndeley commissioned the celebrated American light sculptor to create a site specific piece; 'The Illumination'. Every Friday and Saturday evening this summer, at dusk, the west front of Houghton Hall is bathed in a colour display that slowly evolves over an hour to highlight components of the Palladian masterpiece. Visitors are provided with deckchairs and blankets. Sharing a bottle of prosecco, there is no better way to spend an evening in England this summer. Dreams are made of this.
