They’re the great wonders of the world that every intrepid traveller must have on their wish list.From Ireland’s Giant’s Causeway, Hawaii’s Kilauea volcano, to India’s Taj Mahal and the Great Wall of China, to not see them, really is missing out.A new book by Lonely Planet reveals the top 50 must-see world wonders – with the experts picking out their top 10 especially for MailOnline Travel.World’s Great Wonders brings together the most amazing manmade structures and natural creations from across the globe.From the formation of the fairy chimneys of Cappadocia to the painstaking creation of the Terracotta Army, the book dedicates at least four pages to each site’s fascinating facts, stunning photography and detailed illustrations which give the reader an insight into its creation.The foreword for the book is provided by art historian and BBC presenter Dan Cruickshank who explains: ‘The aim of this book is straightforward – to inform, to inspire and to encourage its readers to travel. ‘If you know key facts about your destination you will surely enjoy it – and most certainly understand it – better. ‘Of course the term “wonder” is loose, clearly subjective and poetic, rather than scientific or objective. I suggest anything that surprises, mystifies, or takes the breath away by its sheer size, beauty or audacity is a wonder.’Jheni Osman, the author of The World’s Great Wonders, adds: ‘This book takes you a step further on your travels, revealing the science and engineering behind how epic structures were built or incredible natural wonders formed.‘It was always going to be tough to reduce all the world’s amazing wonders into 50 must-see sights, but this book spans the heights of engineering, the spectrum of beautiful architecture, and the eons of time.’World’s Great Wonders, which is now on sale priced £19.99, is available through Lonely Planet.(dailymail.co.uk)ANN.Az
