Work is underway on William and Kate's new 'ring of steel' as they set about fencing off a 150-acre no-go zone around their forever home. The Prince and Princess of Wales have imposed a 2.3-mile personal exclusion area around Forest Lodge, a Georgian mansion in Windsor Great Park. It is understood those who venture past the 'no trespassing' signs – intended to keep William, Kate and their three children safe – will face immediate arrest. Another shot shows the enforcement of the car park closure at Windsor Great Park – a move that has proved a particular sore point for local residents. The Grade II-listed Georgian property, nestled in a secluded spot inside the 4,800-acre Windsor Great Park, comes complete with Venetian windows and a hallway with a barrel-vaulted ceiling.
