Reconstruction remains a provocative topic. The author presents a pragmatic perspective on the polarizing, often polemically conducted discussion. The result is a nuanced terminology; for there is no single reconstruction. Through concrete building descriptions and analyses, various architectural concepts are illustrated in their historical development and situated within their theoretical foundations. The architectural and moral dimensions of reconstruction are separated. The question is not whether reconstruction is permissible, but under what conditions which concept of reconstruction can be meaningful. Thus, the book serves as a practical guide for heritage conservationists and architects working with historical structures.
