'The World's Must-See Places' aims to take readers on a tour of more than 100 of the world's sights. Ancient, classical, and modern sights from every continent are included. Each featured sight has been selected for its uniqueness, or its historical or architectural importance, and many are included on UNESCO's list of 'World Heritage Sites'. The sights include iconic landmarks, such as Chartres Cathedral and Sydney Opera House, and lesser-known gems, including the Kairouan Mosque in Tunisia and the Toshu-gu Shrine in Japan. In addition to text that describes each sight, sidebars and text panels cover topics such as the architectural style of the building, the architect and his works, or historic events or people that shaped the building.
