Here is the history of the buildings that have shaped the world in which we live, ranging from Stonehenge and the Step Pyramid, to the high-rises that dominate our city skylines today.

Each page features one building and looks at its history, its builders and the impact the style had on its contemporaries.

Along the bottom is a timeline showing what other buildings were being constructed at that time in other parts of the world and how they reflect the growth of the societies in which they were designed and built.
