This new series in a square format sends the reader on a journey across European metropolises. Thereby, the attention is focused not on prominent buildings at large but on ingenious and extraordinary details. Each title focuses on a different constructional element. The first three volumes present doors, windows and facades from all architectural epochs and styles. Every one includes about 700 photographs that illustrate the diversity of European art of building. Whether new or old, nice or bizarre here the reader will find an architectural kaleidoscope of a special kind.
