European metropolises like Berlin, Rome, Barcelona, Istanbul or London are fascinating because of the history, the people, and the feeling for life – but especially because of the buildings. Architectural details of all epochs and styles are the focus of this book: the window as the eye of the house, balconies as retreats in the midst of the urban din or stairs as the embodiment of change. Aside from their functions, these details lend a building individuality, provide it with a face and determine its appearance. This volume takes the reader on a journey through the plazas and streets of the most exciting 20 metropolises of Europe, presenting an unusual variety of architectural details. Be it something new, old, beautiful or strange, every city appears in a thoroughly new light.
