Not all of the 911 precious and iconic treasures promised recognition and protection by UNESCO, (the United Nations Educational, Scientific and Cultural Organization) could be featured in this gallery, but a selection of the most amazing buildings, ruins and natural wonders are. Think of mind-blowing feats of human achievement like the Great Wall of China, the Pyramids, and the mysterious Maoi of Easter Island, through to natural marvels like the Great Barrier Reef, Victoria Falls and Giants Causeway.
