In this edition of Open Country, Helen Mark explores the landscape at Blenheim Palace in Oxfordshire. The 2000 acres of parkland were landscaped by Capability Brown, and are now a UNESCO World Heritage Site. The grounds are also home to a Site of Special Scientific Interest, and earlier this year a colony of rare bees was discovered in its ancient woodland - surviving descendants of indigenous honeybees which were previously thought to have been wiped out. There are also 12,000 acres of farmland, where a new project is underway to try and make the estate carbon neutral. As dusk falls, Helen winds her way though Blenheim's illuminated trail, where more than a million sparkling lights and lasers light up the winter landscape.
