what does unesco do for world heritage sites
World Heritage Site The sites are intended for practical conservation for posterity, which otherwise would be subject to risk from human or animal trespassing, unmonitored/uncontrolled/unrestricted access, or threat from local administrative negligence. Sites are demarcated by UNESCO as protected zones.[1] The list is maintained by the international World Heritage Program administered by the UNESCO World Heritage Committee, composed of 21 UNESCO member states which are elected by the UN General Assembly.[2]
Stonehenge One of the most famous landmarks in the UK, Stonehenge is regarded as a British cultural icon.[6] It has been a legally protected Scheduled Ancient Monument since 1882 when legislation to protect historic monuments was first successfully introduced in Britain. The site and its surroundings were added to UNESCO's list of World Heritage Sites in 1986. Stonehenge is owned by the Crown and managed by English Heritage; the surrounding land is owned by the National Trust.[7][8]
