ARCH+ is one of the largest and oldest periodicals in Germany that focuses on architectural history and theory. Every issue is devoted to a particular subject, place, or theme; recent topics include contemporary Viennese architecture, social housing design, service architecture, and shrinking cities or the end of Bauhaus. Contemporary buildings are featured to illustrate the topic, while timelines and reference projects are meant to situate the topic in broader historical and cultural contexts. Issues regularly include long-form essays by academics and architects as well.
